If Statement Giving Wrong Output Issue Calculated Column

I have this simple if statement where there are two columns. Column 1 = Score Column 2 = Test

This is the If Statement Code:

=IF([Score]>70,"A","F") 

If the score is greater than 70 it should give an A in the Test Column. If it’s less than 70 it’s F.

The picture below is the issue. Am I doing something wrong here?
