grading papers as a TA

I have a TA that sometimes grades papers.  If she submits grades, it still shows up in my activity feed that I have alerts.  I have to go in and click on all of the same grades and post them.  I locked a class last spring.  My TA did the final grading. I'm still getting alerts about the class.  I can't go in and accept any of the grades because the class is finalized.  It's frustrating.  Any suggestions.
