reflectors

I replaced the brake pads on my panigale v2 stock brembo brake calipers. There's no issue on the right side because of the direction of torquing, but when I try to torque the left side to 45nm of torque, the reflector rotates up with the bolt and won't hold in place. I've tried clamps and zip...

I pulled in to my garage today, and noticed the big reflector that was on the front left fork, laying on the floor. Has anyone else had these fall off??
