I'm trying to make a more like this section. Please Help!

I’ve got a large database of movies that are linked to a dynamic page. I’m trying to add a Wix pro gallery on the dynamic page that contains 8 movie titles that are similar to the title that the user is currently viewing. The database of movies has a genres section which I want to filter by. I have managed to get the gallery to show titles that contain the exact same genres, but I’m trying to make it so that it shows movies that are similar genres and not necessarily exactly the same.
Below I’ve attached some pictures of my collection setup and code and some other stuff. I’m very new to coding so sorry if none of this makes any sense.

I also need to make sure it doesn’t include numbers when filtering.
