See https://translatewiki.net/wiki/MediaWiki:Wikibase-datatype-label/qqq for the message contact. That clearly identifies it as a field label. If there needs to be a message that can be used as a column header, this is not the one. You should create a bug report.

See http://www.w3.org/TR/html401/interact/forms.html#h-17.4.2 for example of field labels in forms.
