One of our workflows is incorrectly creating some folders, and we're trying to isolate it.

I'm doing an Entry Name search inside workflow, which the tooltip defines as "Search for workflows that interacted with an entry with the specified name." However, when I type the name of one of the errant folders, no instances come up.

I know for a fact that the folder was created by workflow. How do I find out the exact instance that has created it so that I can examine its tokens?
