U-phoria 1820 and ADA8200 not 'completely' seen in obs

[The Singing Drummer]

With the two interfaces, I have 16 inputs and around 20 outs.... However, using the Uphoria's UMC asio driver, I can see inputs 1-8, SPDIF inputs, various outs, but definitely not all 1-16 inputs.
Anyone know why and how I can get OBS to see all the ins and outs? My DAW can see them using the UMC driver - but not OBS?

Thanks

I figured I would take a screen shot - can someone tell me how I can get to 'see' or use the other 8 inputs - listed as ADAT1, ADAT2, etc
