Doesn't work "Phys Mat" from "Break Hit Result", from "Component Begin Overlap" event

Hi everyone. I have a problem. When I call “Component Begin Overlap” event, and “Break Hit Result” for getting Phys Mat, Phys Mat is not valid. But another hit results working.

When I use, for test, hit result from line trace, all works correctly, but hit result, Phys Mat, from “Component Begin Overlap” event doesn’t works.
