Do You have read.me text in english?
I think f.ex weapons.ru ale in russian - I have very strange letters....
Can't you just erase the irrelevant lines (in green here) by yourself?
Here's the readme as it is:

and then just add yourself "default", "FAB250", "none"?? Btw, it is not even necessary for the mod to work
