Hi ,

Thank you for pointing this out. I was able to reproduce this issue, and have entered UE-52421 to have it investigated further.

Actually, the ticket that I entered just came back as a duplicate of another one that is currently being worked on. The actual issue here is somewhat more broad than my repro would indicate, so the engineers are going to keep working based on the other ticket.

Hello!

Three months later and I have the same issue! When is the fix going to be available?
