Rear jacks did not extend

[backwater4]

Backed into a unlevel concrete site. Powered up Lci leveling system , started leveling. Front jacks extended,raised front tires about 1in off the ground . Lci panel indicated level. Rear jacks never extended. Any ideas, thanks in advance:

We’re you auto leveling? I always manual level, so I can’t make sure all jacks contact the ground for stability, if not getting level…
