Bug: Magic Mask 2.0 changing selected clips

Hi there!
I'm having some trouble using the new Magic Mask point selector. Every time I click to add a new point to the mask, DaVinci switches the selected working clip to a random one without any additional input, forcing me to reselect the clip and node I was working on every single time... a big time hog.
In addition, sometimes (apparently at random), after tracking the mask, it starts to "fade out" during the last few frames (usually 3–5 frames).
Any thoughts on that?
P.S. Regarding the "fade out" issue, I found a workaround by extending the clip by a few frames, re-tracking the mask, and then trimming out the extra frames I don't need.
