Do "Probe Only" and "Query and Probe" of the CollisionEnabled really work?

Do “Probe Only” and “Query and Probe” of the CollisionEnabled UE5 component collision attribute really work? After I set the component’s CollisionPreset to “Custom” and CollisionEnabled to “Probe Only”, why can the component still collide with simulated objects?

My understanding of “Probe” is that I can use “Probe Only” or “Query and Probe” when I need two objects to produce a collision callback, but I don’t want the simulation result to actually collide. These two options can make the object using it into something like a trigger. Is there an error code in my understanding?

It seems that PROBE only collision and QUERY AND PROBE does not work as written, epic games please clarify the situation

What exactly is this “Probe” anyway? I haven’t found any documentation about it anywhere.

Just in case anyone in the future bumps into this, TateSun’s understanding is correct. I guess there was an engine bug at the time of writing.

“Probe Only” means the body will generate hit results against bodies it intersects, but the collision won’t actually affect the physics simulation, the bodies will simply phase through each other.
