Incorrect Details in CAT form


I got a call from IIM B for the next round process. I noticed while filling a form recently that I made a mistake while filling the CAT form.
I entered my 10th percentage as cgpa10 instead of cgpa10. I entered 96% instead of 91.2%.
I got a call from IIM B based on this. Please advise me on the next steps on who do I need to contact from the admissions office. Also, would I get a chance to fill in these details again in the interview process form? If so, I can correct it there. Please advise.

Thank you
