Destructible Mesh - Line trace gun issues

So I have a Line Trace gun, and I want to apply radial damage to 2 destructible walls. (Radial damage is applied from Out Hit Location)

The first issue would be, that if I hit one wall, it is in the way to the origin of the second wall, and therefor no matter what not destroying any of the second wall. So with this I know what the issue is, but I don’t know how to solve it.
Also if I hit something next to a wall, nothing gets destroyed.

Second Issue is, that I have the walls on top of each other, and I have turned on “Form Extended Structures”, wich attaches the upper one to the lower one. Now I can’t damage the upper wall, until it gets detached from the lower wall.
