Hi, I've tried to mount barbed wire to the top of my wooden wall to stop people climbing in. There is two options, one shows a picture with the barbed wire on the bottom of the wall, and the other on the top. I am able to find the barbed wire on the ground when it is in the 'top' slot, but after mounting with pliers it appears on the bottom (see screenshot). I have another barbed wire to try mount to the 'bottom' slot, but cannot find the wire on the ground (can you tell me where it would be exactly?). There has been multiple restarts and still mounting the bottom instead of the top.
