Trying to give a new bass a good setup, and I'm having issues with the Hipshot Quadrajust bridge. See the pictures. The 1/3/5 strings all have phillips head screws holding the bridge down. However, the screw heads pop up enough that the saddles ride on top of them causing the height of the strings to go up quite a bit. I thought the underside of the silver saddles would be shaved away to allow safe riding over the screw heads. But they seem flat underneath. Is this normal? Do I have the wrong screw heads on the bridge? Seems factory, and I have 2 other identical bridges and basses, and while it is the same, it's not as bad for some reason. See how on the 2nd picture from the side, the B string's saddle is tilted up at the back? That's because it's sitting on the screw head, and thus that's the lowest the string can go, even though it can go lower still. Has anyone removed the 3 saddles and filed them down? Or are there flatter screw heads? am I alone in this?
