Would you mind taking a screenshot of your loadout page and the UI when you have the Vehicle Bay selected?
What is a loadout page?
On the main menu there's a button that says "Loadouts." This is where you select which bonus you want to start with and which vehicles you want to have. If you don't have one configured you get the slimmed down tutorial loadout.
Ok, I've found units I talked about in the loadouts
