Hello!

Hello GrowingTree,
Thank you for the report. Fortunately, I was able to reproduce the issue in 4.17.2 and 4.18.1 and I was also able to find a report for this issue already logged, which you can follow the progress of if you’d like here: Unreal Engine Issues and Bug Tracker (UE-51237)
If there is anything else that I can help you with please let me know or feel free to open a new thread for any other issues you might have encountered.
All the Best,
