We had a very similar situation with our rig just a few weeks ago. Got our hydraulics to the same point as you...........slides in, all jack retracted even though the alarm panel indicated otherwise.

By talking with the LCI support people, and reviewing our condition, we agreed to continue driving several days to get back home. It is now at an authorized dealer to have the situation looked at by their repair group.
Hope your safe also, but call them to discuss.
