Lockdown mode Rap sheet reward issue

I completed the rap sheet progression till gold tier this week and i got the rewards in my profile for bronze and silver tiers except the gold tier which is a Ferrari testarossa, the screenshot shows that the reward as been given but the car is not showing up in my garage, ive tried restarting the game but still nothing, i really love playing Lockdown mode due to these issues my gaming experience is degrading, kindly fix this issue asap. thanks
