Dear experts,

So, I created a new BP class based on my C++ and voila - it is set correctly:

 ![BP_collisionActor2.png](https://d3kjluh73b9h9o.cloudfront.net/original/3X/d/a/dadc5d0f30d0e0279cb1f280076d1f02d8b793d4.png)

Is that a bug? I am on engine version 4.22.3. Is there a workaround to properly update my original BP class with the collision set according to the C++ ?

Thank you for any hints on this.

Best regards, Peter
