iMessage for Mac: only using a bold font

[Capex]

I have this bizarre issue I can't seem to shake. My iMessages will only send in bold. I deselect bold and it just goes right back on its own… I have gone into fonts and selected a non-bold font and the issue persists. Has anyone had a similar problem? a restart does not help.

EDIT: Disregard. Finally fixed it.

What a jerk.
