Duplicate cars inheriting tier points from older cars

I got a duplicate car though a prize crate and later decided I wanted to sell it. What I noticed is that the duplicate took the tier points with it (+110 for the 2016 Honda CTR) when I sold it. Now the original I had says +0 tier points. I know it’s the original because when I check the history it has information regarding its race participation.

So what I ended up having to do was selling it and then re-buying it to recoup my missing +110 in tier points. I did verify that selling the dupe took my tier points and that I had to repurchase after removing the original in order to get my tier points back.

Turn10, please fix this. I don’t want cars I’ve invested time in to end up no longer contributing points to my tier level if I end up getting a duplicate and selling it.
