Hi Alyssa,
You do not have to duplicate the diagram each time you would like to make edits and you should not have to delete the jobs either. That error message is general when there is an issue with the diagram configuration and something that we can look into moving forward.
I am not sure what version you are on but here are a few of things to check in your editing draft of the diagram that could cause that error:
(a) No floating steps: if you are in an earlier version, you must have all steps in the canvas connected by a path.
(b) Duplicate steps: In earlier versions, the steps would sit directly on top of each other making it very difficult to tell if it was somehow accidentally duplicated. This used to be a bigger issue if you tried to drag a box around all steps to move them, it was easy to duplicate the entire diagram by accident. This has been improved now as well as duplicate steps from copy / paste are offset. You can grab each step and shift it to see if there is a duplicate.
(c) Missing required information or invalid value(s) in a step configuration.
Hopefully, this helps!
