Ok, I have attempted to recreate this issue on my end but I have been unsuccessful. Could you provide a test project where this is occurring so I can attempt to diagnose this issue on my machine.
What I will need is ONLY your .uproject, and your content and config folders from you root folder of your project. You can link that via dropbox here you can send me a private message on the forums.
On the forums, to find me, go to Advance search and type in my name in the search for user tab. This will allow you to send me a private message. Please attach the above mentioned files in a link to dropbox there.
