Removing empty or blank rows in gradebook

Hi,

I was wondering if anyone knew how to remove the empty rows that have built up under my class list in gradebook? Some classes have 3-4 extra rows, and others have 10-11 (I've included screenshots). It's not a huge issue, but it looks messy and it would be great to remove them.

Thanks,

Hello Max,
The number of blank rows depends on the number of students in each class, it can't be changed .
