How should I setup my hands in regards to tracksets?

I’m a bit confused here because the Tri Series has two tracksets that require a Med GC car. I’ve noticed that the same players have different hands on those tracks compared to those without the Med GC requirement. I thought the first four races were the tracksets in order, and the remaining ones were random. However, when I played my first four races, I only had one Med GC trackset, and it wasn’t even in the correct order of the list you can see. This is annoying because I know I’m losing points because of this, I have a very competitive hand on the other tracksets in my lobby but I’m being beat down. Am I missing something about how to set up hands, or is this a bug? Cheers.
