This is super nit-picky, I know 
When you get a segment jersey (like with a sprint/KOM), then level up and receive a new jersey, you can’t actually try out/wear the new jersey because the segment jersey is shown on your avatar in the drop shop.
Again, it’s a really nit-picky thing. If I had a nickel for every time this happened to me, I’d have three nickels. Which isn’t a lot, but it’s strange that it’s happened three times…
