Hyoid bone/ muscles over delevoped

[Jdtread]

Recently I’ve been training hyoid bone. I’m already lean but I had a slight double chin. The more I train it the more my “ double chin” sticks out the bottom of my jaw. It’s like a small clump of muscle. Why is this?

Alr maybe I'm dumb but I've seen people trying to mew and end up inflating their submental area, the dude can chin tuck day and night, if he's doing ts it will still look bad
