Issues signing up a Scout

I have a new scout that is in 5th grade but just turned 11 years old today. When I go on to sign up the scout I am getting an error because they are 11 years old. How can I get it so this scout can sign up since they are within the grade requirements for the Cub Scout program? My BSA Member ID is 12864510. The child in question doesn’t have a membership in the system yet.

It has to be a paper app @NicoleBassette
