Family Sharing Problem - Missing 330 Movies

There are 330 movies missing from our library of 380 movies. We have 5 Apple TVs, many Macs, etc. We have 5 family members (3 adults, 2 children). We watch our saved family sharing movies all the time and we know we have 380 movies (among the 5 of us 330 of them belong to my own apple ID - for Itunes, and 50 of them are scattered to the other apple IDs). I have two apple IDs: one for itunes, one for icloud (family sharing). Everyone else has one apple ID. But everything worked well for about the last 5 years. Now, suddenly POOF 330 movies are gone across the family sharing/icloud/itunes combo. I am testing what happens if I login with only my itunes id.
