When playing in editor, if you fire your weapon at a trigger volume, the projectiles will bounce off of the volume, regardless of the fact that the collision is set to Query Only. This collision also generates a hit event even though both the trigger and projectile are not set to generate hit events.

Found in 4.9.2 binary, and reproduced in 4.10 Preview 3, 4.8.3, and Main CL 2749677

Steps to Reproduce

1. Open the editor
2. Create a new FP BP Project
3. Place a trigger volume in the level
4. Fire your weapon at the volume

Result: Projectile bounces off of the trigger volume

Expected: Projectile would pass through the volume without collision
