Has anyone had issues with multiple contact types showing as a result in Search Builder despite contact specification?
Rebekah - from the list you posted MOST of them show both the categories selected. The only ones (7th one down) that I can see that don't have them have a lot of others and may simply be pushing the ones you want to see out of sight.

Perhaps I don't understand your question but from what I see the result looks mostly right.

AH - If you are wanting to find records that ONLY have those two categories then I suspect Search Builder may not be able to do that in one step.

You may need to create a group of those above, and then create Groups for each of the categories you don't want to find, and use the Include/Exclude Custom Search.

Or do this via an sql query
