Dynamic Head is always invalid

I want to upload this custom character i’ve modelled to the Roblox marketplace.
When I tried to upload it, it said “DynamicHead when emoting surpasses the expected bounding box”
So far I’ve tried removing all animations, but that gave this message: “Head.MeshId has inactive FACS controls: Pucker, LeftLipCornerPuller…” and “DynamicHead did not pass threshold (0.000000 < 0.095000 ) for percent change when emoting”
then, I tried redoing all the animations with minimal movement, and it still says it surpasses the expected bounding box.

Is there way to know exactly what bounding box it is surpassing, and how to see it and not surpass it.

you deleted your face bones or they aren’t near your mesh
