I have a Mission EP1 RJM which I always thought was crap and wouldn’t calibrate. I had it set to Type 1 which the manual suggests works for most normal expression pedals. I figired they would include mission as “normal”. Anyway, i eventually changed pedal to Type 2 in the system menu and all of a sudden it worded perfectly. Try that and see how you get on.
Thank you I will try that!
