Why is the Vanwall in rotation for some dailies and not others?

This is the WEC-Xperience selection:

And this is the One-Stint Sprint selection that has the Vanwall:

Is this a mistake? I might try the Vanwall in WEC ranked just for fun in the future and would like to know if it's worth driving it if it's not going to stay in rotation.

The crashing with the car is meant to be fixed in the most recent patch:
