Steps to Reproduce
- Make a new Actor Blueprint
- Add a new CollisionProfileName variable
- Compile and save the blueprint
- Add two instances of the blueprint to a level
- Change their CollisionProfileName properties to have different values
- Select both Actors at once
- Notice that the property does not properly handle the multi-selection
- Select each actor individually and notice how one of their CollisionProfileName property got set to the value of the other
