Hi,
I’ve taken a look at the project and I am having a hard time reliably reproducing the issue. There are a lot of different variables that may be causing it. Have you tried this in a clean project? I’m unable to tell if it is the engine or something within it. Would it be possible for you to send me a simplified version with only the assets needed to reproduce the issue along with the steps that you are taking to reproduce this?
-Thank you
