Mistake on CSU application of colleges attended!

I already submitted my CSU application, and have been offered “conditional acceptance” to CSULB, but I found a mistake on the information I put in. Under colleges attended and transcript entry, I only added Santiago Canyon College and put the classes I am currently enrolled in under Santiago Canyon College and not Santa Ana College. All the transcript info is correct, but just this semester is under the wrong school. However, Santiago Canyon College and Santa Ana College are sister schools, and when adding/enrolling in classes they are in the same website. What should I do?
Also, CSULB is asking for my transcripts from Santiago, so should I send both Santiago Canyon and Santa Ana Colleges transcripts or email?

Send both of the transcripts.

Email the admissions office at CSULB and let them know that you have classes at both of those CCs, and to watch for the two transcripts. The admissions office will be able to help you sort this out.
