Scout's Grade Level is Not Editable

I was just updating my Scout’s School Information in Internet Advancement after seeing that the issue with it was fixed, but while the School is editable, the grade level is not. All my scouts have the correct Grade Level except one. His grade is too high. I also have another Scout whose current school shows up 15 times is there a quick way to delete these or do I have to click the X next to each one?
