mark/unmark in emplode

The Mark/unmark feature within EMPLODE does not seem to be working yet. I have few songs marked. Edited their metatag, as I intended, and removed the "mark" from within emplode. Sync. Still marked. Maybe this was not mean to be fixed yet, I don't seem to remember this bug mentioned in the release notes, still, I wanted to mention this in case instead it WAS supposed to be fixed.
