Mine works perfectly - My bolts are different and they are black not silver. Also the slider tracks on mine are smooth, without the positioning holes. They obviously have revised it. On your one, i would get a thin flat file and grind down slightly the bottom notches, so you can slide it.
So you wanted it to adjust it but it seems like is too tight on one side than the other. I just got mine and yeah is hard to get right balance but you can get it to work properly.
