I've got a LP Tribute and I'm sure the hardware is different; code is similar.
But if the pot works properly otherwise and you've tried this on multiple patches, I'd have to think that it's a software issue (but) and not something that is 'broken' from a hardware perspective.
I have an analog sequencer that has a 'dead spot' around 2 o'clock on the dial and it's tricky but if I use a quantizer which I often do, I can send the same normalized voltage (I really should replace it).
One test you can do is go into Precision mode so that you see the values and very slowly swing the pot from 0 to end of range and see if it's smooth, all values represented with no jumping.
Otherwise, reach out to Amos directly and give him the precise info such as code version (including build #), and the steps you take to reproduce the problem.
