Weird issue listing movies - Not showing up in whole library listing.

[RLanger7228 73]

I am using Emby Version 4.9.1.90 on a Synology DS 718+, running DSM 7.2.2-72806 Update 8.

I have been adding movies related to Marvel & X-men recently.  Screenshot 1 shows them in the recently added section of my home page just fine.

When I look at my whole movie library listing, sorted by date added (most recent first), only one of those movies appears - SS 2.

When I sort the whole movie library listing by Title A-Z, only one of the 8 X-men movies I know I have shows up. - SS 3  

I edited the metadata so the TITLE field is the full title of the movie, but the SORT TITLE field is "X-Men ##,"  with ## being the 2-digit chronological order # of the film in the story universe.  All the X-Men film's full titles also start with the letter X, so I don't understand why they aren't listing in the X section of the full listing.

This is a problem that I can't imagine a cause for.  The movies are present on the NAS when I look them up with File Station.  They show up automatically in Emby on the Home Page (SS 1), when I search for them using the magnifying glass, and in the X-Men collection I created, where with the sort order title they appear in chronological order.  Why don't they show up in the whole movie library listing by title or date added?

I just noticed that another movie titled "Zotz" (and a whole handful of other Y & Z titled movies) that do not appear at the end of the alphabetical listing either.

Not visible from your screenshot/image cut-off: do you have any filters enabled in your library view (icon would be blue colored)?
