Your symptoms are classic height sensor issue and or calibration.
If I have my LLAMS set on minus -20mm and I am parked on a flat section of road and I go to access height I have no issues but if parked on a slope I get the same fault as you - car is is trying to lower at one end than it should.
So you have a sensor that is out (maybe the one you have just fitted and not calibrated) so as suggested get a recalibration done.
I have found that when you lower to access and you get the gong and it says it is raising I hit access height again and hold to lock and it does then actually go down and stay down - so maybe a short fix until you get it sorted.
