Removing/editing historic unincorporated place names that are out of use?

I cannot find a way to report a map problem for an unincorporated community name label that shows on the map. Specifically, the historic CDP (Census Designated Place) "Arnold" shows in many maps but has been out of use for many decades (it's arguable whether it was ever in use). The area labeled "Arnold" on the map is actually within the incorporated City of Rice Lake, Minnesota. It is not a recognized neighborhood, unincorporated community, or any other type of community with a name. The city administrators would prefer to see the label "Arnold" removed from all maps, as it it not used nor recognized in the vernacular, and is not (nor ever has been) an official administrative unit/place. How do we request removal of it?
