As you can see on the official BBC One page, season 13 only include the 6 "Flux" episodes.

"Eve of the Daleks" and "Legend of the Sea Devils" are special episodes that are listed in our specials season.

As of today, there are no newer episodes.

IMDB has never been an official site.

Thanks for answering and you ar right IMDB is not official site. BBC One is and the official name for season 13 is Series 13 not "FLUX".

I found “Eve Of The Daleks” in the move section but I can’t find “Revolution of the Daleks” and “Legend of the Sea Devils” anywhere.

And the downside with specials as movies is that it’s hard to watch chronologic. Its easy to miss those “episodes”. Hens I go to IMDB for easy watching guiding.

Season 13 was called "Flux" at the time of its broadcast : https://www.youtube.com/watch?v=xDUvFdGu6JE&list=PLKEzuOOEQvYN4bvzMFxoReLWsDO3x-Ql4&index=3

I found “Eve Of The Daleks” in the move section but I can’t find “Revolution of the Daleks” and “Legend of the Sea Devils” anywhere.

They have nothing to do in the movies. "Eve of the Daleks" has been removed from there.

They are not listed as movies, but in the special seasons of the series.

It is Series 13 now. By calling it Flux you would be fighting imdb, wikipedia, kodi scrappers and rest of the world. And causing problems for people using this site in Kodi as they have to figure your way of media library structure and get confused when David Tenant shows up again in late 2023.

The important thing is not how it is named now, but how it was named at the time of the original broadcast.

The Doctor Who YouTube channel link description refers to the story being called Flux, it never actually mentions the season. Everything I'm finding from the main BBC sources referring to the season itself seems to have always referred to Series 13 being the actual season name. Is there an actual BBC source which says the season was also called Flux instead of Series 13 or is that just speculation on a YouTube video description of the name of the story that occurs in Series 13? On top of the description not mentioning the season anywhere it seems extremely unlikely they'd go back and rename a season after it aired this one time, what's the evidence of that occuring vs a misunderstanding of the name of the storyline vs season?

The Doctor Who website maintained by the BBC calls it "Series 13 (Flux)" on the Stories page and "Doctor Who: Flux" here. The BBC Media Centre also calls it "Doctor Who: Flux" here and here.

Thanks for these, reviewing:

• The first link seems to indicate the full title is "Series 13 (Flux)" as you noticed, not just "Flux" as it's titled on TMDB. At the same time this also includes additional information on several other series titles also known to not be part of the core series title (both by the BBC and TMDB) such as Series 7 having Part 1/Part 2 appended and split. This may imply Series 13 is the main identifier and Flux is an subidentifier, aligning with the usage of (parenthesis) for Flux in the first place. But we'll see how the other sources treat it to get a more firm idea.
• The second link doesn't really seem to offer much to say about it one way or the other. It says "Doctor Who: Flux is premiering" and separately says "the new series is premiering", we know both of those to be true regardless what we take the series name to be as the story and the season premiered at the same time.
• The third link again confirms the 6 part serial is titled "Flux" but then later also directly mentions the series was titled after it. It also refers to the season as Series 13 in several places, including "Series 13" the article title which is shared with "Doctor Who: Flux" - the title of the story again. This seems to align with the first link in that, at premier time, the series was perhaps titled "Series 13 (Flux)".
• The fourth link is saying the trail for the story is entitled "Doctor Who: Flux", not that the series is entitled "Doctor Who: Flux". You can see that mirrored in the title of the trail in the originally discussed link here. The title of this article itself being "Doctor Who Series 13" not "Doctor Who Series Flux" (or even having a mention of Flux) seems to back that up.

Based on the first and third links I do see some solid evidence from your sources it was originally at least sometimes titled "Series 13 (Flux)" instead of just "Series 13" at premier in honor of its sole 6 chapter storyline but no evidence the series itself (not the story in the series) was ever plainly titled "Flux" alone. This understanding the series itself was never solely titled "Flex" also aligns with the current naming instead of assuming an otherwise unexplained, unsourced, silent post-air rename of the series to the name containing "Series 13" across the BBC, including the name in the iPlayer picker itself.
