Bug Report Blackmagic Ultrastudio Pro with multiple inputs

Dear all,

we use OBS Studio on Windows with a Blackmagic Ultrastudio Pro, connected on USB, to stream with a professional camera. The camera is connected on Component input of Ultrastudio Pro and it works fine.
Now we'd like to connect a second camera on the HDMI input and configure a new source in OBS Studio, so we could switch between the two cameras from within OBS studio by selecting the configured source.

So I created a scene, added a source called "Blackmagic" where the settings are "Component" as input.
Then I created a second scene, added a source called "Blackmagic HMDI" where the HMDI is set as input.

The meaning was to be able to switch between the 2 scenes to select between the 2 inputs of UltrastudioPro. But it doesn't work and has funny appearances:
- Sometimes, one or both sources don't display at all
- Sometimes, the HDMI source displays only on the scene configured as "Component", and vice versa

...but having both inputs available, seems not to be possible. Any hints?

Thank you a lot in advance,
Raff
