Modules do not appear in the Gradebook, so I am assuming you are referring to the graded content included in Module 7. I guess I could also assume that you might be asking for an Assignment Group called "Module 7".
Unpublished assignments do not appear in the Gradebook, so you may want to verify that the assignments in Module 7 have been published. Learn more at https://community.canvaslms.com/docs/DOC-10101-4152180493
If it is a "Module 7" assignment group that you are looking for, it might simply be that it did get created. have you verified that you have a Module 7 Assignment Group?
If I have somehow missed the mark, please clarify what you are asking, and I will do my best to help.
