Crew ultimate Edition change expansion?

I've been playing the Crew ultimate Edition for a while. But as soon as I start the CD on the PS4, the extension starts: Calling all Units. But I also want to play the other games. Does anyone know how to get to the other extensions?

It all takes place in the same world, there are then only new dealers on the map for e.g. At Wild run there are monster truck dealers. These are just DLCs that run in-game

Edit: look for "The Summit" on the map, has a big S. There you will e.g. Introduced to drift, drag, monster truck missions!

There's the crew 3 and 4?

Yes. But I think only for Xbox

There's only The Crew 1 and The Crew 2.

For me it says that there are also 3 and 4. If not, I'm sorry to have given incorrect information.
