I've got the same issue with the Param / Category and Value / Preset knobs on my KeyLab 49. I'll turn them multiple times with no reaction, then the next click jumps them several rows down in Analog Lab.
Likewise, if I'm using them to move thru parameters and values for the KeyLab itself, the value/preset knob tends to skip one on every third or fourth click clockwise, and when going counterclockwise, it'll not change values for one click, then skip a value on the next click, doing this every third or fourth click.
It does seem that these knobs are buggy in that regard. It's just a minor annoyance, but if it's something fixable in a future firmware update, it'd definitely help the navigating experience.
