Tags showing as Tag Prototypes when viewing related Function

Tags have been created in our system in two different ways, via SSIS (and into the Stage tables) and via the eB Provisioning Spreadsheet (executed by Bentley Professional Services personnel).

All Tags appear in eB correctly when viewing a Tag directly.  However, when viewing the related 'Function' that has been assigned to any of the Tags, they do not appear as a relationship.  Rather, they appear under the 'Tag Prototypes' topic in eB Director.  Further, the templates used to create these Tags does not have the 'For Prototype' checkbox selected.

Why are any Tags in our system displaying as Tag Prototypes when viewing their related Function?
