Interesting. I would like to test this on my end if you are willing. If you would provide a link to dropbox with your .uproject Content and Config files from your project files. I will then attempt to recreate this issue on my end to determine whether this is a bug or not.
If you are uncomfortable with posting a link here you can go to our forums and send me a private message. You can do this by going to the forums, clicking the advanced option button, and navigating down to search for user name. Enter my name there and you will be able to send me a private message.
