Canon shutter won't respond to sequence setup

When I set up a sequence with my Canon R, the shutter does not stay open for the duration of the set exposure. Is only performs a quick open/close. In Backyard EOS, it works find. So I believe its a setting problems in SGPro. Any advise

My guess is that you’re enabling mirror lock up with BYEOS and not disabling it prior to using SGP. In any case you can disable Mirror Lock from the settings menu of the camera. We do not currently control this setting in SGP.

Thank you,
