sorry for the late response. i think i know what the issue is and how to fix it but im going to have to test it out first
go to your settings and click on display on the left side of ur screen, tick off "code editor" and "profile text" in the little boxes. pretty sure that disables wysiwyg which is whats fucking the code up. cant say for sure but im redoing his code rn without wysiwyg to see if that'll fix it
