End workflow action inside of Run if action - Issue

[vigoriton]

In my workflow (which is pretty long), I have a check to see if the item status is one where no more processing is needed and if so, end the workflow. This is done by having an End workflow action inside of a Run if action. This "works" as the workflow ends but when I look at the workflow history it there seems to be a problem as seen in the snippet below:

Looking in the detailed view, in the Action History section it says that the Run if action started but is incomplete and End workflow action completed. Also, in the Workflow messages section I see the following: Event: Workflow Completed, Message: For more information, please read this article: http://go.microsoft.com/fwlink/?LinkID=323543&clcid=0x409.

What could be the issue with this? Thanks in advance for any help!

Nintex Workflow uses SharePoints workflow engine.
My testing showed that if I created a SharePoint designer workflow configured the same way I received the same comment in the workflow History.

This appears to be a SharePoint issue.
