PLEASE HELP: strange problem in Plex web with a certain library's collection tab

@BigWheel
Since yesterday, I have the same phenomenon again.
But this time, fixing it via “my own way” does not work any longer.

Therefore, once again I have to “reset” all apps by “Restore Defaults”… I really hate to have to do this again and again and again.

BTW, I updated to newest beta yesterday AFTER it happened… and it did not help.
