Hi Donna,
I have found the below in CA documentation. Please see if that's what the issue is about.
Data is not loaded in the Data Warehouse if English is not added as one of the languages in the Data
Warehouse setup. This issue occurs even after the Load Data Warehouse job completes successfully.
Add English in the Languages field of the Data Warehouse Options (Administration, General Settings,
System Options). For example, if Spanish is the only language you need, you still have to select both
Spanish and English for the data to load successfully in the Data Warehouse after the Load Data
Warehouse job.
