It seems that when you published the process from Studio to Orchestrator you didn’t choose the Source files option.
Republish the project and then check again.
Note:
-
Include Sources - select this option to package all
.xaml
sources within the published package, including workflows that were previously made private. For Windows - Legacy libraries, the files are saved in the generated assembly file and in thelib\net45
