Multi Capsule/Sphere not detecting any collisions

I’ve noticed that in my project nodes like Multi Sphere Trace and Capsule are not detecting any collisions despite collision channels being correctly set.

For example I have an actor with a simple static mesh that blocks visibility, and in the mesh model I’ve set a collision shape. In my character blueprint I made a Multi Trace Capsule by Channel whit visibility as the collision channel fire when hitting the left mouse button. The capsule appears as I have tested it whit debug display, but it doesn’t detect any actor at all. I’ve tried with other channels but the result is the same.

The rest of the blueprint is not important for the purpouse of the question, as it is only the capsule node that is not working.

Someone knows what could be the cause? Thank you in advance.
