Agent Forehead gets cut, only small square around face get's animated

When I generate an agent, the only animated area is a square containing the facial features.
Any Hair or hats above the forehead and below the chin get cut and stay static, so that the head looks jagged.
This does appear even when using your preset avatars like the redhaired girl with the bun. The bun get's "cut" and stays in place.

This makes the agents kind of unusable.

Important to say: the idle animations work perfectly fine. Bun get's animated, so does the forehead. Same when generating videos. It's just the agents.

Is there any design-tricks, that I need to know or is this based on what plan I have?
