Sounds like you may have air in the system and need to cycle all cylinders full stroke several times to purge. once done, if that does not resolve the problem, you may have a leaking seal in the cylinder that will need to be replaced as the cylinders are not repairable per Lippert.

First, check fluid level with all slides in and legs up. Fill to approx 1 inch from the filler neck.

Then extend the cylinders full length in the order of front legs, rear legs, curb slide, road slide and last bed slide unless you have a vanity slide and it would be last. Then retract the slides in the reverse order and legs last. This should be done at least 3 or 4 times.

Once done, retract legs and watch for any creeping. There is a five year warranty on the hydraulic system.

Good luck and post your findings when you complete the repair.
