can someone have a look at this please :)

It is likely to have been deleted.
The link you posted is from a Movie.
But I believe that in fact this title is from an episode of a TV Show.
This is the TV Show
https://www.themoviedb.org/tv/61864-good-witch
And this is the episode
https://www.themoviedb.org/tv/61864-good-witch/season/0/episode/4

Is that the title you are looking for?
If this is the case then your link has been deleted

Morning Yes this is the case thank you, but these were stand alone films in their own right? :) If the link has been deleted then why does it still show up in the list? just a though :)

There are several others that can be duplicated.
Only by doing a one-by-one check is it possible to say.
For that it needs to be someone who knows this TV Show.
