Default [Q] Poweramp - Manual Folder Selection very slow

Hi there,

I'm using the paid version of Poweramp on a Samsung Galaxy S3 running Slimkat-ROM (4.4.2).
When I try to select my music folder it took approx. half an hour before showing the tree. I have a 32GB external SD-Card.

The external SD-Card also shows up twice:
- /mnt/media_rw/sdcard1
- /storage/sdcard1


Can anyone please help me with this issue?


Thanks
Selter
