( NOW IT'S SOLVED) Cannot get config to show up

I'm new to Beam.NG, and I decided to do a skin mod. I followed all the instructions. But when I went to make a config, it didn't show up! Also, I tried to make it a police one so I could catch suspects as well, but it did not register either. Please help!!!

 

One easy thing to do would be to checkmark "include user-defined pc. configurations" in vehicle selector. Did you do this? I don´t know exactly the english phrasing ("benutzerdefinierte pc.Konfigurationen einbeziehen" it says in german version).

 

That was it. Thank you!

I'm trying to get it to show up without having that switch ticked.

I found what was wrong. I was saving the configuration not using the skin internal name. Bye!
