Folder deletion deletes all folders starting with same string

[Yu24]

In Android 13, playerpro v5.39 folder view.
if folder with name e.g. "1" is deleted, this deletes all music in all folders in current parent folder which start with 1.

Howto recreate:

Create folders with music files in them:
1
1.bla
1-blup
10foo
13 bar

Delete folder 1 in playerpro.
This deletes music from all above folders.

See screenshot.

Thanks
