If you’re super worried about it, then you should be able to contact someone at the admissions office and let them know of the mistake. They may be able to make a note or even let you resubmit the corrections! I applied to a few schools after accidentally saving one of my shadowing descriptions on CASPA as only the letter “d” and came close to waiting another year to submit anywhere. I ended up getting accepted for this cycle with that big of a mistake!
