Won’t allow me to Auction Hennessy venom

Recently I bought 3 Hennessy venoms by accident. I used tokens, i accident because it kept saying their was an error
And the purchase couldn’t go thru… after trying 3 times same message kept coming up. Anyway. I gave up and went to my garage. Turns out the cars did go thru and they charged me each time. Now that I have three when I only needed one, it won’t let me auction it. It doesn’t come up when I go to set up auction… anyone have any idea why or how I can fix this?
