Using 3.3.7261 P.
I have three highlighting rules set up to display on the left side of Tracks view in the main panel. One for No BPM, one for No Volume Leveling, and one for No Lyrics.
I selected all the tracks on an album and ran my BPM app and the No BPM highlights disappeared as expected.
I ran Volume Leveling and the No Volume Leveling highlights did -not- disappear. I checked and Volume Leveling had been applied.
I ran the lyrics finder and the No Lyrics highlight did -not- disappear. I check the tracks and for the most part, lyrics had not be applied.
I did a File Rescan and there was no change. I shut down and then restarted MB. No change.
I rolled back to 3.3.7257 P and upon relaunch all the highlights disappeared.
I reapplied 3.3.7261 P and upon relaunch the highlights returned even though the criteria was met for them not to be showing.
I tried a different album and got similar behavior. I then displayed my entire library in Tracks view and all were showing the highlights even though, once again, the criteria was met for them not to be showing.
