 I have inadverdently set all 6 settings in Register/recall.  QUESTION  How do you delete/erase or change these settings I have searched and can not find an answer. 

After reasigning functions in Custom Buttons they will revert back to default. I've probably set something somwhere else that is overriding the new functions. I can't find it!  For Ex I'll set a new function to the shutter button when I go back to it...
