Missing train cars and wrong names

[Shaunof99]

I don't know if it's a bad installation of Ottd or one of the gfxs, but some of my train cars will not show up in the depot when buying new trains. Ex.. there will be no option to buy a metal car or an iron ore hopper. Also, a lot of the time, the name will not match the cargo. Ex..the grain hopper will show it hauls coal. Is this a bug or incompatibility somewhere, or should I just reinstall the game and try again? I've been running FIRS.

You need vehicle grf which supports FIRS. Default vehicle set doesn't work properly with extended cargoes.
