I just noticed a mistake on my application

I recently found out that I got accepted into Cal Poly for CS and I wanted to look over my application one last time and I noticed that in my 10th grade year my orchestra class was marked as an AP class. I just emailed the admissions office, but how bad does this look? Thankfully I have backup options but will this likely get my admission rescinded?

If you had other ap classes that year, you’re fine. Only one honors class from 10th grade counts for extra grade points, so your cal poly gpa won’t change.

Ok, that’s definitely a huge relief.
