I recently got a new phone. I copied contents of sdcard on old phone to a new sdcard and put in new phone. I used Samsung Smart Switch to transfer settings/apps to new phone. In my new phone, I have a duplicate playlist for every playlist. One playlist will have m3u in the name and the other will not. The playlist files are not duplicated on the sdcard. Only duplicated in Poweramp library.
All music is stored on sdcard in folder named MUSIC. All playlists are m3u stored in the SDCARD\MUSIC folder

I tried Rescan/Resolve Playlists but no effect
At one point, all of the playlists were duplicated under Internal Storage -> Music folder. I deleted those manually from My Files app.
Thanks
