I experienced this same issue. So +1
I am currently running version 18.104.22.168 which is available as a Beta, and I am not able to replicate this issue.
Please update your version to the Beta and confirm if this is now resolved.
Sam, I am running version 22.214.171.124 as it is the latest version available out of beta. Picked up 126.96.36.199 and it is working properly.
Glad that this is now resolved.
When duplicating a show, all the information of my banks and programs are transferring over, but my fixtures aren't and my patch bay is blank. Therefore, my faders don't appear on the program tab.
Has anyone else experienced this issue?
