Sagging air suspension after ready lift installation

[Funky6rudda]

Air ride suspension sagging front drivers side.
I got new wheels and tires installed as well as the ready lift 1.5” leveling kit two days ago. Ever since in the morning my truck has been sagging down at the front over night. The first day I woke up and it was completely bottomed out on the bump stops. It wouldn’t raise up for a long time until I actually got to work (I know it wasn’t the best idea to drive like that) so I went beach to the garage and they said they re calibrated the shocks and they don’t think that’s the issue but couldn’t see anything else causing it. They are not specialists at this and the guy was blaming the sensors because of the lift. I explained the sensors have been moved so as far as the truck knows it’s the same height.
Anyway having owned an old LR3 I have some experience with leaking air suspension. But I am wondering, since they discounted the shocks to install the leveling kit maybe they either didn’t reconnect them properly or there isn’t enough nitrogen in the system? Any ideas thanks

Might want to ask this in the suspension sub forum.
