Agptek rocker - button mapping issues

[Kalessinthedragon]

Using my newly rockboxed agptek I encountered several issues that obstructed me from using some features:
1. On playback screen after holding down I cannot adjust the shuffle setting as hitting left redirects to the pbs.
2. Holding up on pbs does no longer give me the option to adjust pitch etc but redirects to the home screen.
3. I cannot adjust any colours in any of the settings as left/right redirects me to the previous screen instead of adjusting the scrollbars.
Is there a way to remap buttons, is this a problem on my end or is the button mapping still work in progress?
Tnx for any advice.
