Mask Expansion broken

I'm using Premiere 24.3 on an i7 3.6ghz PC with 64GB Ram and a GTX 1080. The masks in Premiere seem to be over-spilling in their expansion. I first noticed it with masks in Lumetri, and now with Opacity as well. I have supplied images. The over-spill is by 100 when the shape is uniform, but when the shape is stretched, the over-spill becomes larger on the side with the greatest distortion away from the mask's center. No errors were given.
