(UNSOLVED) How do I make it so that every vehicle spawns with a random license plate?

Hello!
Quick question. I do a lot of RP scenes, and use them for videos and or screenshots. Whenever I set my default vehicle with a custom license plate, like JACK for instance, I spawn a new vehicle, and it's JACK again. Whenever I just do a randomized plate and set that as my default, which was 8CB0722, it literally was that plate for every single car. How can I make it so that every single car has a random license plate?

I do have "Use Steam name for license plate" disabled.

Thanks!!
