PC A Question Regarding Gwr Diesel Legends Pack

This one had been on my wishlist for a while and I finally grabbed it during the recent sale. I mainly got it for the Class 31 services, but I enjoy the express runs and Class 101 occasionally, too.
Anyway, what I found is that on those express services (Paddington-Reading), I can't seem to be able to get anything more than a bronze medal. When I looked at the preview stream by Matt and Sam, there seemed to be 'Go via' objectives along the route at various stations. However, when I'm driving I only have one such point at 'Gantry 8-1' shortly after departing Paddington, after which the next objective is to stop at Reading.
Was this pack updated at some point after those streams that changed this or am I doing something wrong?

 

I believe only bronze is possible on most of those runs. It certainly won’t be anything you are doing wrong.
