Trace Channel colliding even if the channel is set to ignored

I’m using 4.11.2. I have a vehicle (Skeletal Mesh) with the mesh collision set to collide except for Visibility and Camera. When I run a Line Trace, it will collides with the vehicle even when the Visibility is set to ignored. I ran debug and it is actually colliding with the simple collision boxes from the physics asset.

Is this a known bug?

Are you setting the collision settings in the class blueprint? I have had issues where there was an instance already in the level that fails to automatically adopt changes made to class blueprint

Its set directly in the blueprint…and you’re absolutely corrected. I don’t touch any of the instanced objects to avoid that very issue. -_- I hate it. Thank you so much OM.
