Thanks to both Rich and Tim:

Fluid level is good and I see no leaks.  I'm thinking Rich's suggestion that it may  be a sensor is a good one.  I will contact tech services and see if I can get more specifics.

Thanks again.

My left rear leveling jack does not full extend on auto mode.  Works OK on on manual mode.  On auto mode the two front levelers extend.  The the right rear leveler extend to the ground.  Then left rear leveler extends to the ground.  Then right rear leveler extends further lifting the left rear leveler off the ground.  The the auto system stops with the left rear lever off the ground.
