Business process task created by Open Edit Page not closing when Progress bar set to save record on stage change

Hello,

I have a business process that opens an existing record. The Open Edit Page is set to mark the element as completed when the record is saved and the progress bar is set to save the record on stage change. 

But the business process task is not removed from the list after the stage changes, and the record is saved. The only way to remove the task from the list is to click the Save button on the page.

Is there a way to mark the business process task as completed when that happens? Or even better not to create a business task at all when using the Open Edit Page? 

Thanks,
Jose
