In the previous version, when I chose a mask preset after hitting "K", and then exited mask mode with another "K", that same mask preset would load automatically when I hit "K again. Now it seems that I need to re-choose a mask each time I go into mask mode. The previously selected mask doesn't load, or at least, it doesn't load properly.
Sometimes, the mask loads as "edited", with all the settings set at midpoint. Or the mask that loads is named "custom", again with all the settings at the midpoint.
