Assign 18-19 CSP to students

I am unable to assign the 18-19 version of the CSP course to students. Am I missing something?

When you go to Classroom Sections, click on the arrow (see picture) and select Edit Section Details. You will be able to assign the curriculum version in the next window that pops up (see picture).

When I look at the section it does display the version 18-19. I will have the students check their accounts again today. Thank you for the help.
