Get-PWRichProjectReport and Work Area Types

In my datasource, Get-PWRichProjectReport creates a spreadsheet with four tabs. Two of the four tab names correspond to two of my four Work Area Types for the datasource.

Two tabs in the spreadsheet are named differently.

If the tab names are to correspond with available Work Area Types, is it possible renaming of the Work Area Types at some point has created a disconnect between the spreadsheet created by Get-PWRichProjectReport and the currently defined Work Area Types? Are the tab names unique to the -FolderPath perhaps?
