Category/Subcategory Report "multiple" as a value

Content

We created a report to pull out all Answers by Category and Subcategory including different Categories/Subcategories for the same answer.  We were able to yield the results we needed however now all of a sudden the value shows as multiple and we're not sure why?  What filtering can we use to yield the results we need?

Attached is the definition of the report and what it yields if it helps.
