text: You've already removed the shop=bevareges tag 12 Minutes after node creation (see other note http://www.openstreetmap.org/note/539824). What the reason for this note?
  Did you perhaps mix up changeset comments and notes? If you changed something already, usally there's no need to create a note. 
  At more complex changes, needing more time (like the new roundabout at Nievenheim), mappers may do this sometimes to keep multiple mappers active at an area up-to-date. But you don't have to do this for small, completed changesets.
