When the program has been running for a while, such as after ripping multiple discs. There seems to be a bug in the metadata categories drop down list. The list seems to get longer and longer after each disc is ripped. The dropdown keeps adding the complete list of Music genres.

Say you want to add the UPC tag to the disc you are ripping. You press the plus button to add an extra tag element. When the program if freshly opened, the list of tags available contains only the standard metadata categories. Then after the next disc is inserted the dropdown list grows to include the metadata categories and the music genres. Then after the next disc, the metadata categories and 2 lots of the music genres. Once a few disc are ripped, the list ends up beings hundreds of items long.

I am using dBpoweramp OSX v. 17.7. 2020 M1 MacBook Air running macOS Monterey 12.4.
