Strange formatting glitches

The formatting is messed up, everything is set to default, but when I add any new text it turns gold. maybe it has something to do with that little line beside the line. if i edit any other lines they also get this beside them. originally some of the text was pasted in, but that was removed and everything on-screen was typed.

Another unrelated issue occurs when I try to continue a line after a footnote, its all superscript.

File is docx.

Any advice on this?

Thanks, that was it. I’m an idiot. not a clue how it got turned on though.
