Distance to Assets Geocode Assets and Bases model fails to open in Pro 2.1

[BobBooth]

There is a core issue in Pro 2.1 (ArcGISPro/ModelBuilder#226) with models created in Pro 1.4 that is affecting the Distance to Assets Geocode Assets and Bases model.
The same issue is affecting the Geonames Locator tools (https://github.com/ArcGIS/solutions-defense-test-catalog/issues/65).

The solution for the near term may be to use the ArcMap version of the models.
Pro dev team seems to be working on this, but I have no information about the time frame for a fix.
