Overview discrepancy

I have a discrepancy between Overview and actual albums and tracks, I seem to be missing 51 albums, 907 tracks, any ideas what’s happening? Or how I find them?

When you state “actual albums and tracks” do you mean in your folders, or as counted by Roon when you click Albums or Tracks under Collection?

If you mean the counts in Roon, then I believe this is duplicates - the overview counts all albums and tracks and the Albums and Tracks view does not count the duplicates.
