What is up with the masking tool

Hi,  What is up with the masking tool, I make a mask, I set it to Subtract or something else, I set a keyframe, it goes to add, I change it back to Subtract, I move one or a group of points, it goes back to Add, I set it back to Subtract move the whole mask, it goes back to Add.

This is super annoying, and a major BUG!!!!
