CV GPA Mistake

[ms4gradschool]

I recently submitted an application for a Development Studies program. My undergrad university scale is out of 9, and the GPA I entered within the actual application form was higher than the stated requirement out of a 9.0 scale. However, in my CV, I converted my GPA into a 4.0 scale and the converter I used showed a GPA below the 4.0 scale requirement for the program. I used other converters after the fact and it showed my GPA as higher than the 4.0 scale requirement for the program - I should have done this before and used the more accurate higher GPA. My question is, now that I've already submitted the application, they have my transcripts, and both my GPA out of a 9.0 scale (higher than requirement) and a 4.0 scale (lower than it actually is), should I tell the admissions department that I made an error on my CV and ask to resubmit with the more accurate 4.0 converted GPA? Or am I worrying for no reason and should just leave it as is?
