Have you tried restoring to previous save after noticing this?

I had a similar issue where the Exhaust upgrades for all my cars had gone BUT just restoring to a previous save after noticing this problem when I first started the game and all my upgrades came back.

It might be that the latest save hasn't got downloaded and saved on you device and instead has been saved to FM's server.

It does occur to me a few times on various things like servicing of cars that didn't finish.

Don't do anything after noticing the problem, just restore previous latest save.
