When using the ImportExportCLI command the above error message may be displayed. The reason is that deleting a dynamic property of a Workflow does not delete its overriding values in its executions. Therefore, creating the same property on the workflow leads to the above error.
The same behavior can be seen for other overriding relationships such as when a Deployment Package overrides the dynamic properties of its Component.
The ImportExportCLI command should behave the same as it does when the same operation is performed from the User Interface, which is:
Example: An execution override /tag1 of a Workflow. Deleting /tag1 value of the Execution is not allowed.
