I was able to reproduce your issue. I have submitted a report (UE-7021) to the development team for further consideration. Thank you for all of your information and time. I will provide updates with any pertinent information as it becomes available.
I was able to reproduce this issue on our end. I have written up a report ( UE-10285) and I have submitted it the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your information and time.
There are two issues listed here. I went ahead and checked on both of these issues for you. It appears that UE-7021 has not been resolved as of this time, however, UE-10285 has been fixed internally and will be available in a later release of the engine. I hope that this information helps.
