The field is for the "TVDB ID" i.e. a bunch of digits. I looks like there are a few issues.

Only the TVDB episode ID (eg. 7825487) should be saved when an episode link is entered: https://www.thetvdb.com/series/384983-hook/episodes/7825487 That's something Travis has to fix. In the meantime, please add the ID manually rather than copy-pasting the full link.

The series link https://thetvdb.com/series/detention-2020 does not include the TVDB show ID 387152. This one should not save at all. The series ID has to be entered manually.

Same issue with TVDB season IDs. There is no season ID in your link https://thetvdb.com/series/345645-show/seasons/official/3 As far as I know, TVDB retired seasons ID years ago. Just leave the field blank.

Ok got it. Thanks!

Nerd alert!

Indeed, TVDB does not display season IDs anymore. But they're still available in the source code of those pages. For example, go to:

https://thetvdb.com/series/345645-show/seasons/official/3

Now use the function of your browser to show you the source code of this page. Then search for the series ID (in this example 345645) or for the string

data-id     

In this example, you'll find the number 1886512 - that's the correct season ID that you can enter here:

https://www.themoviedb.org/tv/78798/season/3/edit?active_nav_item=external_ids

I did this maybe 10 times in the past, and it always worked. Also, if there's artwork added to a season on TVDB - like in this example - you can spot the season ID in the url of the image:

Thank you!!! that worked so well!!!
