Q2
I was able to reproduce this and have submitted UE-24810
Thank you for taking the time to demonstrate this in a clear and concise way! It’s much appreciated.
This should be resolved during the process of the 4.11 Preview builds, but I cannot confirm which preview release this will be fixed in until a developer has had time to investigate and submit a fix. For that reason, it is recommended to work in a stable build like 4.10 vs the previews which are known to have issues like this.
Thank you again!
