2004 Porsche GT3 Saved Tuning Setup Problem

Every time I reload a saved tuning setup on this car from a saved tune the game charges me 5,000cr – Odd since I already owned all the parts. I accepted the 5,000cr charge, saved the setup again, and reloaded the saved tune just to see… and the game wanted to charge me 5,000cr, again.

This is repeatable, but only on one of two 2004 Porsche GT3’s I own. One that was a career award is fine. One that is a “Special Dealer” car (that I bought at the Auction House) is the problem child.

Investigating, I noticed that the homogenization parts become un-owned when I select an alternate part in its catalog. No other car I own acts like this.
