Hello! I presume you're interested in this node (https://www.openstreetmap.org/node/153943762/history). If that's not the case let me know. 

The data error you mention predates my cleanup work but definitely points to something being wrong. My best guess is the error was introduced in this changeset (https://www.openstreetmap.org/changeset/34636544) by merging perviously overlapping bank and place nodes. The bank information and place information appear to have been re-added independently leaving this as an extra (and erroneous?) node.

I have move the extra bank tags to the bank and adjusted the county relation to use the other place node as the "admin_centre". Does that seem right to you? https://www.openstreetmap.org/changeset/145050802
