Noticed that the other day:
Your Direct Lean value will reduce by 1 each time you touch anything in your controller setup. Had it set at 100, and after messing with my settings, I realized it was at 88...
Reproducible easily - set it at a value, close it, open the setup again, fiddle with another value (may only work in the first page of the settings), validate, open the settings again, the Direct Lean will have gone down by 1.
What a weird and random bug!
Thank you for the report.
The bug has been fixed.
