Not all assignments being restored?

Hi, All:

I've backed up a course (on crteacher2.com) and am trying to restore it into a new course (on classroom revolution.com).  The problem is, not all the assignments seem to be showing up. 

When I look at the list of files that will be backed up and restored, they are there: but they are not visible on the home page for the site.

Any help would be really appreciated!

Thanks,

Michael
