Description of Issue

Roon shows a lot of my albums twice. The “false-positive” duplicate albums are all showing to the same files on my QNAP. There is no different version of this file. If I use the inspector to find duplicates, it shows hundreds of such false-positives. How can I get the albums shown only once? I think the database is here somehow wrong.

Hi,

I’m wondering if you have two duplicate or overlapping watched folders.
Can you share a screen shot of Roon’s Setting → Storage page.

As a trouble shooting step, have you tried rebooting the Roon Core?

[Cosmic_Encounter]

Yes, I rebooted the core already.
here are the screenshots:
