Cannot save changes to a workflow step. (4226910)

It is not possible to save changes to one of the workflow steps.

The following error pops up each time you try to modify a workflow step and save changes:

An item with the same key has already been added

Other workflow steps can be edited and changes can be saved.

You might have several workflow steps with identical ID (number) in the same workflow, for instance two Step 2 items.

WORKAROUND

1. Delete one of the steps with the duplicate IDs
2. Close and then re-open Quick Connect Administrative console
