Duplication in Resource Group Efficiency Report

When we run the Resource Group Efficiency Report, we are getting duplicate records for “Department: INSP / Inspection”. The options we use are shown here:

In the report here, you can see that each result is listed 4 times.

The report itself is the stock/system SSRS report, and the DD that is used is also the stock/system one.

The only thing that I can think of that may be the issue is if the Resource/ResourceGroups are setup incorrectly for INSP and INSPFIN. Anyone have any idea where to look?
