Career Mode Issue

I like to report a career mode issue that I have started to replay the career mode and after I went through the beginning of the story, when I get to the part where I get my first car, it would not let me switch to Buy Stock and it’s just Buy Custom and it just like malfunctioned for some what weird reason and I tried every possible method but none of it worked, I will also ask that it’s because of the updates and it will not keep up with the current updates and it will just mess up the single player mode. I don’t know but I just moved on to the online multiplayer mode and I will just move on from playing the career since I already played it millions of times. 🤬😫😞
