I have noticed that while navigating through Artists (browse MPD database by Artist) and when hitting the back button, it will sometimes take you to Dirble (null) or to Genres. That should not happen IMHO.
I have also noticed that if you change/correct any IDv3 tags, that the changes are not picked up and used and the old tags remain in the MPD database even after you go to Menu->Sources and click on Rebuild MPD Library.
Has anyone else seen these issues or is it just me or am I simply missing a step somewhere?
Any help/advice would be appreciated.

I am using the following equipment:
Raspberry Pi 3 Model B
Raspberry Pi Foundation 7inch Touchscreen
Logitech Z333 2.1 Speakers (via RPi audio out)
SanDisk Ultra 8GB Class 10
