Duplicate of private "android/media" folder

Within "settings > Miscellaneous > Default directories > Set custom sub-directories" I selected "Private 'Android/media' folder" for "Set maps/" and "Set mapsVector/"

Regarding the info in the "Set custom sub-directories" screen, the path for the maps/ directory is now: "/storage/emulated/0/Android/media/menion.android.locus.pro/Locus/maps" - where I copied my maps files - and this is working!

But locus automatically also creates these files one level up in the the path, so 2 empty folders: "/storage/emulated/0/Android/media/menion.android.locus.pro/maps" and "/storage/emulated/0/Android/media/menion.android.locus.pro/mapsVector

If I delete them, Locus is creating them again after Locus' next start. So why Locus creates this unnecessary, duplicate folders?
