Collections randomly lost movies but display art still shows them

[zellonatious 3]

A lot of my collections have randomly lost a lot of movies that were in them. The number of movies lost varies from collection to collection. The artwork for the collection still shows them but they're no longer in the collection. The movies themselves still exist on the emby server. Not sure when it occurred. I recently updated to 4.9.3.0 a month or two ago.

Is there any way to recover the collection state?
