It is worth verifying that in level mode the front left is inflating properly. In travel mode, the two front airbags are controlled together by the center front ride height valve. In level mode, as Richard mentioned each airbag is feed independently based on signals from the computer. I would also verify that the level sensor in the top of the bay hasn't gotten knocked out of whack send extremely erroneous information to the HWH computer.
