Replacing an F grade CUNY

Hi, I am not sure where to post this but last semester, I received an F in calc 2 and over the summer I have retaken it for an A-. This is my schools policy on Failing courses:

“Failing Grade: An undergraduate student may repeat up to 16 credits of failed courses; if the subsequent grade is C or higher, this subsequent grade will be included in the calculation of the cumulative GPA. The failing grade(s) will not be included (although the course and the grade remain on the record). The cumulative GPA will be used in determining if College admissions, progress, and graduation standards have been satisfied. F grades will be used in calculating the GPA for graduation honors and may affect the determination of admission to specific programs and progress in specific majors. If the subsequent grade is a D, both the original F and the subsequent D will be included in the GPA calculation.”

From what I understand, the F should not be included in my cumulative GPA but when I check my GPA on CunyFirst both the A- and F are averaged into my cumulative GPA. What I am wondering is that I have attempted 61 credits including the one F grade. Shouldn’t the 3 credits from the F grade get removed leaving me with 58 credits accumulated?

Any input would be greatly appreciated. The F is really taking a hit on my GPA and it is worrying me. Thank you
