So I'm going to first post a DeepL translation of Max4vettel's comment as it appears he and I are having the same problem:
"I installed the mod and the names of the teams and drivers appear wrong, for example in red bull I see pastor maldonado and perez, what did I do wrong?"
So, same here, certain drivers and team names are wrong, as in they're the default names from vanilla state F1 2014, but for example all nationalities are set for proper 2022 drivers list, leading to, for example, Chinese Marcus Ericsson driving one of the Alfas instead of Zhou Guanyu. I followed the installation instructions so I too am now left wondering what caused this problem. Other than that, mod looks and drives great (though my amateur self has to use the old handling model to keep the car on the track).
