Vp Abellio Class 380 Reskin Input Mappers Not Working?

I installed Vulcan Productions' ASR reskin for the Class 380 add-on, I own both the Glasgow Airport Rail Link and the Class 380 standalone, but the keybinds aren't responding to any input, yet the standard Class 380 works completely fine just like any other train. Any reasons or fixes as to what's happening?

 

You would be better asking Vulcan Productions on their Contact page
