Add on cars and menyoo new cars not showing

[aramgi7]

Hey Guys,
So just today i decided to add more cars (Add on) onto my gta 5. Bare in mind i've already added some cars a while ago and they spawned and it was working perfect. So i load up the game and use the trainer to spawn the car. I check Simple Trainer first because it has its own section for "added vehicles" but the slots showed no cars. Then i went onto menyoo and i pressed the Super section and it had like 7-8 cars that were brought out when the game first came out?

So community i need your help on this because this is quite strange.

Thanks,
Aniket
