Lippert Auto Leveling system operating questions

Ours has the Geound Control system, once I get the trailer where I want it and before disconnecting from the truck, I pull the pins on the front legs and lower them down to about 3-4" from the blocks I use. I then turn on the auto level, hit "jacks down" . Once it stops I disconnect, extend the rear jacks, then hit the "auto level" button and watch it dance.

I've had an issue with it once and used it many times in almost two years of owning this trailer
