How to change collegiate graduate gullet

hi,
I was wondering if anyone on here knows how to change the new gullets in the new graduate saddles? The instructions say there is a screw on the inside but there isn’t and I can’t find any videos online. Any help is much appreciated!!

Thank you, I did watch this but where she describes to unscrew it mine has a silver circle but nothing to put a screw driver in, I see someone commented this but they didn’t have an answer

Further in the comments of that video there are some other folks saying that they needed to contact Collegiate and get those replaced with actual screws as it was a manufacturing error. I’d advise contacting the company you bought it from (might be able to send you a replacement if it is brand-new) or if it’s older, maybe contact Collegiate directly?
