when I try to use the shape feature on the 90degree feature It does not seem to shape symmetrical, I am using a 90 degree engraver

I bought GRS Apex sharpening system, and try to insert the QC gravers to polish, but it is very hard to let graver get right angle with Dual Angle fixture, this linkkzfaq.info/get/bejne/latioLKmsNTZcWw.html (How to Use: The GRS Quick Change Sharpening Fixture) show how to ling up when we insert graver to collet, but if I try her way with Stone setter QC graver Knife or Flat graver #40 or #38, or QC Graver Onglette/PT 2/0, the graver can not be right parallel with collet's slot, neither with Dual angle's silver protrude part. would you have have a video show us how to use APEX black fixture Dual angle. how to make stone setter's graver insert to Apex Dual angle fixture in the right angle?
