This is a side-effect of a recent fix implemented to resolve the speed issues plaguing the site for the last few months. Not terribly long ago, I added in a check on custom submissions that only allows the original user to revise them. This check was poorly-coded and was overloading the database server. So, for now, revisions to custom submissions are temporarily disabled. In the near future, I'll be implementing this check in a better way and from there, will re-enable revisions to custom submissions. In the meantime, you can either wait it out or post your revision here and a staff member can directly edit it in.
