issue with Mini panel in beta2, chroma warp - exp not workin

on the mini panel, "exposure adjustment" of new chroma warp is not working in beta 2. in beta 1 it's ok but beta 2 not working.
Also, for my mini panel, don't know why, it's still the same as resolve 19, some of the knobs, when i rotate it, the number would increase or decrease suddenly, this always happens when I first open resolve, after a while after those parameters have been changed, it's ok. but for new parameters the issue is still there, i have to reset the knob by pressing it, and then rotate it again.
