I would guess that you have a leak in one of the fittings of the rear air bags. Easy enough to have this after having new bags installed.
I would start at the fittings with soapy water and go from there looking for a leak.
On the auto level, the HWH system bypasses the pressure switch that controls the 120V air pump, enabling the pump to go to a higher pressure when the auto level activates. Depending on the pump, and the age of the pump, different max pressures can be reached. In my observation, it takes about 110 psi to raise the rear of my coach.
