Common App red dash under "Writing Supplement" column

First of all, why does it say “Not Required” when UNC actually needs the applicants to submit their own UNC prompts? All the universities I have applied to say “Not Required” under Writing Supplement column.

The Common App does not even allow the applicants to submit without the college-specific writing supplement. And in the Review sections in Common App before I pay, the specific prompts for all the universities that I have applied to are showed in the very last page. So why does my Common App have red dash instead of a green check-mark for every universities I applied to?

It’s a bit hard to follow what you’re saying but the more selective colleges usually require a supplement, which could be an essay or a resume. When you’re doing an application through the colleges website instead of CA, you usually have to do an essay(s) because they don’t have your CA essay to look at. If the supplement is not required than you can submit fine. Also, in the supplement section there should be a space for you to type in. If the supplement is for sure required and there’s no place for you to type then I would contact CA.
