Only the Services that are assigned to the Categories being measured for that report will show up. 

So, if you have a Service Group with 4 assigned Services, the Wellness Report is only using Parameters assigned to one or two Categories. For the Categories that only have 2 Services assigned, only those two services will appear on your report.  Even though the Service Group has 4 Services assigned.

Step 1: Hover over [Systems] → click on [The Wellness Score®] → click [Setup] → select [WS Settings].

Step 2: Click on the [Categories] tab and [Assign Services] to the related categories.
