To clarify a couple points:
By "Batch Edit" I mean "Bulk Edit"
By "Grades" I mean the "SEO Score"
(in case anyone was unsure)
Finally as I look further I notice all of the posts when I go in to analyze now say "save the post again to re-analyze" it. So that's a workaround too but this glitch still forces you to open all the posts and do something with them to find out what the "actual score" is, which it shouldn't (when bulk editing) IMHO.
