"Wrong category" when trying to join a mp server

Hey everyone, I'm having some issues when trying to join a multiplayer server. I've figured out all the mods/tracks/etc and it plays great on single player practice, but when I try to join online I keep getting a "wrong category" error message. I'm assuming this has to do with my bike category because it keeps populating as "?" when I attempt to join online.

Here is a screenshot of my bike setup in the main menu (top) and what it keeps changing to when I try to join online (bottom):
