This error is submitted from Navmii GPS.

It looks to me as though a wheelmap user has confused the cycle rental station with the square of the same name, and a subsequent, new, user has compounded the error by adding additional tagging that applies to the square as a whole. As that user only made two edits, it is not worth starting a changeset discussion.
