Any HWH control panel setting other than "Travel" should isolate the HCV's from the air bags. Those setting will isolate the air bags from all inputs unless "Raise", "lower" or one of the "up" or Down buttons is being actively pushed.
If you can get the rear raised at all, does it stay up? If not, then (when the control panel light "Travel" is off) if the rear drops you most likely have air leaks related to the bag installation.
