"Another user has completed this task" after BP is completed

I have a business process with a preconfigured page that collects a few pieces of data, creates some related entities and then opens an edit page for one of the created records.  Everything runs fine, but after process execution and after the record is loaded in the edit page, I get the message "another user has completed this task".  Nothing is set to run in the background and the process is not set to run as system user.

Any ideas on how to prevent this message from showing or what's causing it in the first place?
