Not Hiding Movies In Collections

Hi,

I’m having a problem with one of my collections. I have over 100 collections all working find in that the library is set to hide any movie in a collection and does what is expected. I added a “James Bond” collection recently but when I add files to it the files appear in the library as well as the collection. I’ve recreated the collection with a different name but still get the same issue. I’ve also set the advanced property on the collection to hide items that are in it but still no luck.

Any suggestions of what else I can try?

Server Version: 4.63.0 (Windows).
Client: NVidia Shield & Web

Regards

Bobby

Are the affected movies in several collections at once?
Is the collection a “smart” collection (i.e. one created with a library filter, instead of manually adding the items)?)

The affected movies are only in 1 collection. It’s a manual collection created by clicking and Add To/Add to Collection.

Only thing I can think of that’s different is the Plex Server got upgraded recently…
