Need Some Editing Help

OK so I was adding the last few issues of a Justice Leagues series DC partnered up with General Mills to do as a promotional thing (if you ever get a chance to read them do! They are interesting, fun mini stories. Me and my little brother have been having a blast trying to collect them). Anyway when adding the page I accidentally forgot to upload the cover image. Tried adding it after though I seemed to have screwed up. If anyone can help thanks!

General Mills Presents: Justice League #8

@crazyscarecrow: I took care of it, next time just go into edit mode and you should see a flag icon in the bottom right corner of the cover, if you hit that and refresh it will be made default.

@pikahyper: Thanks for the help man!
