We had an issue with the bags not filling on our trip last weekend.
We had set up on a Friday - extended the jacks. Before I retracted them on Sunday - I played with the manual adjustments (it was pouring rain and I was trying to tilt the coach and get some of the water off the slide topers before pulling in the slides) - the ride felt a lot bumpier than it did when we drove in.. :-)
I got about 2 blocks thru the campground and then extended the levelers again - and retracted them. The bags then filled up and we were fine.
Are you suggesting starting the motor letting the air pressure build to 75psi, then shutting off the motor and retracting? On ours - both the jacks and slides can only be used when the key is out of the ignition..

I experienced this situation also. It's not that the jacks aren't fully retracted, the problem lies in the sequence of events that you use when retracting the jacks. When the jacks are extended the dump valve (air) opens, which in turn releases all air pressure. Air pressure has to be above 75 psi before retracting the jacks.
Since I have followed this sequence I haven't had the problem rise again.
1) Start coach and let the air pressure build above 75 psi.
2) Retract jacks.
3) You are ready to roll.
