Hello @iamboram, I believe this is a limitation in the pivot table visual. Any field that you add into the values field well will return an aggregation on the field. For string values that will be either count or count distinct. Your best bet will be to switch your visual from a pivot table to a table visual. It won’t function exactly the same way, but you should be able to format the visual closer to your expected output.
I will mark this work-around as the solution, but let me know if you have any remaining questions. Thank you!
