Going over your problem,
Pump works, we know because of your over filled bags
Solenoids work cause your air pump filled bags
Height Sensors front replaced , rears tested ?
No leaks
If your rear sensors test good, then what may be going on , is, your air suspension module may have changed the normal ride height higher for what ever reason.
The one thing I noticed you have not mentioned, and that is, the air never releases to adjust height when, say , in park after a drive.
You have a set ride height, plus 1" higher , minus -1" lower , from set ride height, yours does not move I assume.
Solution, take it to your local dealer, tell them all the new parts, no leaks etc, have them hook up to your module, from here they can tell all about what your system is doing, the can also, check and reset the ride height to proper setting.
Would like to see this problem fixed for you.
