1) In which mapping table (the selection on the right) are you 
changing settings?

2) What exactly are you mapping to the buttons?

3) Is the problem that the change you make don't show up in the table? 
Or is it that the buttons you think should trigger the assigned action 
don't trigger it?

If you can upload screenshots somewhere or mail them to info@iospirit, 
this would probably help understanding the problem a lot.
