Entered A-G Coursework Wrong?

Im asking this for my friend –

So basically he took Journalism this year as a senior and when he was entering in his coursework onto the UC application, he thought it was considered an English Class and entered it under the “b” credit section, so it looks like he has two English classes now. He already submitted his application, and didn’t realize his error until he was filling out the CSU App which lists Journalism under “g” (Elective), where it should be. Will this be a huge problem, especially if he gets in to a school and has to send his transcripts which has Journalism listed as an elective? Or will they see it as an elective on the applicants of our peers and bypass the mistake/how should he try to change it is possible?
Thanks

tell him to email admissions
