OSC is sent via the IAC bus and Generic Remote not recognized

I’m attempting to set up Open Stage Control as a Generic Remote but despite being properly configured Cubase doesn’t detect any incoming MIDI activity. OSC is sent via the IAC bus which is selected as the Generic Remote. Are there any other settings that would prevent a device from being detected?

Interestingly Dorico does register incoming MIDI data so the settings in OSC are correct.
