I'm running Studio One 4.... not sure if that has much to do with it.  I've attached it as a Mackie control master and 2 Mackie Extenders.   Added them to a group, so it should be banking 24 channels.
I've also tried connecting them as 3 HUI devices, but I still have the same issue... it only banks 8 channels at a time.
