Engl Hardtailer Trem Block System

I don't know if my unit is faulty or but the unit is rattling if I move the unit around and its not the screw against the trem block its the unit itself that is rattling. The holes that are pre cut that you use to change between hardtail and no blocking are drilled to large and because of that it doesnt sit perfectly still in the holes.. I had to put some superglue in the hole and now I cant change hole anymore and now its in Hardtail mode always and it doesnt rattle anymore but it takes half of the function away from the unit.. Also the big brass screw that touches the trem block clicks really loudly when you return from dive to neutral position and some dampening should be shipped with the unit but no..
