Hi RapierApe, and welcome on this board.
Sorry you're encountering this issue.
The reason is because on preset loading, GUI knobs and sliders values are not sent to the minilab mkii, which leads to jumps when first tweaking any linked knob.
Please note that when using analog lab 3, Values are sent to controller on preset loading.
Time to work on a solution on a future update.
Sorry for the inconvenience,
best,
