Group Projects - Grades Won't Hide or Stay Hidden

[eskolnick]

Is anyone else having a problem keeping grades Hidden on a Group Project? I am set to Manually Post Grades (under my Gradebook's Grade Posting Policy), but when it comes to grading a Group Project, they are not hidden after I post the grade.

If I manually go in and re-Hide the grade after it's auto-Posted, the setting soon seems to change itself back to Posted.

This isn't happening with my individual student projects -- only the Group Projects.
