Running latest Build.
Now I've two different Library's running.Main and Secondary.
If it was the last update i can't say exactly,because i didn't use the secondary Library a week or two.
Tags in Library's are different. In normal View all is Ok.
But in Theater View the Files disappeared.(Secondary Library)
The cause was my viewing rule from the main library. There are no tags for it in the second one.
Then i have checked options.When secondary Library is activated the Viewing rules from main library are still there.
Theater View is mixed up with Main & Secondary Settings.Things i deleted from main library in Video like Youtube,Netflix etc.,are there in secondary because it is standard.Is Ok.
But Viewing Schemes i created myself in Main Library are also there in the Secondary Library.
And that's why my Files disappeared from there because of missing tags.
It has been working well before.
Please Fix this.
