Multiple Assign activity replacing variables

Ran into several occurrences of variables that have been added to the multiple assign activity that get replaced with one of the other already existing variables so that it is duplicated and the other is missing. This replacement seems to happen randomly and at times where you are not even in the multiple assign activity. (Studio 2019.10.4)

@JoeKaucher can you please share an example of a workflow when this is happening?

Did you edit any of the already existing variables/arguments in their panel? Or maybe have you used Ctrl+Z?
