Question / Help OBS and Blackmagic TV Studio HD

We do a multi camera live FB stream. The camera HDMI outputs go into a BM micro HDMI to SDI converter on some cameras and other cameras plug directly into the BM TVS HD HDMI ports. We tried using a BM micro SDI to HDMI to feed from the PGM SDI output into an AVerMedia device into the computer via USB. Whew. We can see the camera inputs from the ATEM HDMI Mult-view on the monitor, but there is no signal into OBS. If we move the SDI from PGM to Multi-View SDI, then a multi-view will show up in OBS. We then have to take the picture from each camera and resize in order to get two cameras to show in OBS. Then we can transition from two cameras using the cut switch from the ATEM. I guess my question is why OBS doesn't see the signal from the ATEM PGM so that all we need to do is punch in the camera we want to see live (or Program)?
