Audio Issue

I am trying to get an issue resolved for my boss. He is conducting an interview monday morning. To record my boss we use black magic equipment. We also run everything through the Black Magic 4K UltraStudio program. I have everything set up to UltraStudio correctly. The video is going into Zoom with no problem but for whatever reason my external mics are reading in UltraStudio but not in Zoom. Any tips would be helpful because I am at a loss.

Thanks!
