Cross Section Report - Gradebook - ORD 2021 Release 2 Update 10

Hi there! Before hand, I appreciate the help, it's amazing to see the answers you all come up with. 

I have run a corridor and am working on creating a cross section gradebook report. I've created a cross section named boundary, but when I run the report, the gradebook comes up empty. Am I doing something wrong there? 

Thanks in advance, I really appreciate the help. 

Thanks!
