Blacklist Car Not Awarded

Despite extracting with Ronnie's Custom Nissan GT-R Premium Edition '17 from Lockdown and completing the contract for doing so, I have not been awarded the car.

I extracted Ronnie's GT-R from a session of Lockdown, but it was another player's car that they left behind and as such, I only had temporary access to it and did not complete the contract for extracting the car.

In the following game of Lockdown, I found and extracted Ronnie's GT-R from a Lockup (as spawned by the game, not another player's car) and completed the contract for doing so. However, I was not awarded the car upon completion, and once the Jacked version of the car was removed from my available rides in Lockdown, the car was not added permanently to my inventory.

I have since found and extracted the car again, but as the contract has already been completed, I have not been awarded the car and am now locked out from obtaining it. I suspect that there was an issue awarding me the car when I completed the contract since I already had temporary access to it.

I have attached screenshots showing that I have completed the associated contract, and that the only GT-R Premium Edition I have is Izzy's, despite the fact I should also have Ronnie's.
