Need for speed payback derelict error

Hey guys. Excuse me if you see any mistakes, English is not my first language. So, I was plying some nfs and I was trying to collect all the derelict pieces. The only one left is the Volkswagen Beetle 1963, so I collected almost all the parts from it but the only one left is the Accessories, the one that you have to jump to another mountain. At first when I did the jump and grab the Accessory part it was all good it appeared the message that my new derelict was ready,,, but when I go to the menu to the Derelict section it appears that, the Volkswagen's parts list wasn't complete. The only one remaining is the Accessories. I went back to the same place and it wasn't there anymore like I already took it. I don't know if it's a bug from the game or a glitch or something! Console that I'm plying it PS4! Please help! I really want to Beetle.
