What version is your server. What OS is it installed on. Does it happen with all libraries? What type of library is it? Have you checked for database [corruption](https://support.plex.tv/articles/201100678-repair-a-corrupt-database/)?

Had the same problem, using Version 1.19.5.3006
Filtering for duplicates just sat showing nothing and had a very high CPU usage.
The database curruption technique worked to stop the high CPU usage…
The duplicates option now appears but does not show any duplicates when I have several I know of.
When creating a custom filter for duplicates it shows nothing when either true or false is selected.

This has been reported in a few other threads. This one wasn’t the first, but it’s the most active:
> [@Version 1.19.5.3006 duplicate filtering not working](https://forums.plex.tv/t/version-1-19-5-3006-duplicate-filtering-not-working/608750):

> I’ve tried this on both the web app and the windows app. I can filter libraries by other categories, but not by duplicates. I get an error that “There was an unexpected error loading this library” if i click retry it goes back to unfiltered.

When I applied the update (keep in mind, yesterday, I reboot servers, clients, wiped browser cache…nada.
But this update this morning to: **Version 1.19.5.3021**
And the broken library works perfectly again.
edit: to be clear
DID _not_ get to the corruption fixing sqlite commandline steps, was not necessary.
