The Grounds overrides Rapid+ Specialization back to Power Header+

I am having a major issue with the updated progression system in The Grounds.

I selected the Runner Specialization to get Rapid+, and I equipped it into my PlayStyle+ slot instead of Power Header+. However, every time I load into a match in The Grounds, the game completely ignores my choice. It overrides my build and forces it straight back to Power Header+ instead of keeping the Rapid+ trait.

My profile isn't broken—the game code for The Grounds matches is glitched and refusing to load the new Specialization. Please fix this quickly so we can actually use the traits we choose!
