Why are my trucks partly auto-repaired in garage while auto-repairing is disabled? (NewGame+ mode)

I rescued Chevrolet Kodiak and delivered it to the garage. After that, the truck became repaired despite I have the following rule:

Garage vehicle repair rules: repair is paid at 6 times normal price

I didn't buy any addons, only looked at cargo addons. The truck became fully repaired except for fuel tank.

What the logic is here? This happens the second time in my super hard walkthrough with hardest NewGame+ settings.
