Line Trace By Channel never Show hit results

Because of some reason, the line trace never shows Hits results. Maybe the problem is the output actor (hit actor), I don’t know, can someone help me please?

I created this channel called Weapon, to black everything. But even though I change the channel to camera or visibility, The trace never shows the hit results. I tried with Basics, Geometrys, And Actors. Nothing happens. the Curious point is… The trace seems to really block in something, because it never goes forward, the trace ends exactly in the “hit actor”. But the problem is, it never shows the hit results. I also tried to “print string” the hit result, but nothing happens. I definitely don’t know what’s going on. :frowning:
