Hello Fritsl,
When reading over your post the first time, I thought that you were talking about User Interfaces. However, after looking over your reply I was able to understand and reproduce this issue on our end. I have written up a report ( UE-32217) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
Make it a great day
