Howdy everyone,
I have just tested out this issue and have been able to replicate what has been occurring. I entered Jira report UE-11269 into our bug database so that the issue may be resolved in a future release. I have also just seen that the Report has been fixed for the 4.8 version of UE4. I am unsure as to when this version of UE4 will be released but I will be sure to let you know as soon as I hear anything.
Thanks and have a great day!
