I don’t think you understand how to manually raise or lower your six point level up system... the manual over ride works just fine provided you manually open the solenoids with an Allen wrench and use a cordless drill wot( 1/4 bit to run the hyd pump
Lipperts instructions are decent but vague on where the solenoid are to manually override the level up system...
If you bleed your system as I stated and still get creeping front LG then you either have a solenoid that’s not fully closed ... and this can be caused by the manual override screw on solenoid not being secured OR you have an internal leak on one of the two front LG..
Nothing else will cause this..
I’ve attached my version of Lipperts six point level up manual override steps ... your unit will be similar.
You have to locate the manifold where the left and right mid/rear levelers solenoid valves are mounted as well as the front LG solenoid..
You manually open either left or right mid/rear solenoid valve and use drill to run pump motor to retract or extend. Close valve manually and repast for other side...
Same procedure for front LG... solenoid will be either on left or right front LG..
I’ve also attached links for Lipperts easy to follow steps to bleed your hyd system... and how to test for internally leaking hyd cylinder.
If you don’t have the skill sets any competent FV repair tech can do the internal bleed check in less than 15 minutes

In the future NEVER crack open a hyd line on the level up system to manually extend or retract levelers or slide outs..
If someone told you this is how to do it they simply are wrong and don’t know the system nor do they have a clue about what they are talking about
