On the Church Admin Plugin, under App Settings. When I make the Address list style “Alphabetic individuals” it is only letting me check and save a couple of our member types. I can check them, but as soon as I save it goes back to the previous selection.
If I make the Address List style “Alphabetic households”, then check the member types I want to display, then save. It behaves the same as above, except the member type descriptions become numbers.
