Since the latest update, I'm seeing duplicate songs showing in the song list under all songs. I used the library listing to actually delete duplicates over time and found that I'm deleting all the copies of the song. In looking in details of the song, they both are referencing the exact same file. I searched the device and confirmed there is only one instance of the song. Deleting one of them causes the only file to be deleted.
When comparing the file counts on the device, it's about 14413 songs which is much higher than the device has. I moved the music folder elsewhere and the library in Power amp emptied but the duplicates came back when restoring the folder. I've tried rescan and full rescan with no change.
build 934-939 Full version showing this symptom on Galaxy S20 (android 11) and LG V35 (Android 10). Stock ROMs for both devices.
Library is 9 folders with 9831 songs split among the folders mostly evenly. It's a mix of wma, MP3, flac and m4a files.
