My courses are divided into quarters. I want my gradebooks to only show assignment groups from the current quarter, Q4. Even using the grading period filter, I am still seeing a bunch of groups from earlier quarters. None of their assignments are in Q4 and none of them can be edited, moved, or deleted. They are cluttering the grades I need to see and I don't need the kids getting confused by a bunch of useless "totals." How can I remove them from my current gradebooks?

In my attached photo, you can see an endless line of groups after "Total." All I should have right now is the first two before it. Its a brand new period and I should only have one assignment and one post-assessment, thus the two assignment groups.

Any insight would be greatly appreciated.
