T-CAM Color changes randomly for AI Drivers

[ATSSHD 13]

Why does the T-Cam color changes randomly race to race in career sometimes?

For example i saw Bottas, Leclerc and Gasly with black T-cams a lot, and Hamilton, Vettel, Verstappen, Ricciardo etc with yellows (season 1)

One race everything is alright as it should be they have their default colors and on the next weekend the t-cam colors are completely random, no idea why.

It's a little thing but irritating tbf. Only happens in career.
