Thank you Andrew, I'll look into that.
I may not have been totally clear explaining swapping the mini-levers. I did not actually swap out new ones, I just just moved the lever in the middle (for tilt) over to the left mini lever (for raise/lower) to see if the issue followed the lever when I moved it. It did not, so I swapped them back afterwards.
Can these mini levers lose "teaching" without being replaced?
I will definitely look into it either way and post my findings.
Thanks for the response and the manual.
