When using a model with the new feature "Calculation Groups", the Map Viewer is not showing the correct information, the efect is that is not able to show any value in the map points.
This is the calculation group Feature
A new model property visible in the Tabular Object Model (TOM) has been introduced, DiscourageImplicitMeasures. Currently, in order to create calculation groups this property must be set to true
Whe think that this is causing the ARCGis Map Viewer is not showing any values.
This is a BUG and important issue with corporate customer
For your case, it is new feature "Calculation Groups" and not sure it is bug or other problem,
