Missing A-10C textures

[Xeno426]

Hopefully this is the right forum for this question.

I recently downloaded the Who Am I A-10C skin, and modified it to work in DCS World in a non-replacement manner. To this end, I renamed all the files and converted them to .dds format. For the description.lua file, I used this

livery = {
   {"A-10C_PAINT_1-a", 0 ,"A10C_whoami-a",false};
   {"A-10C_PAINT_1-b", 0 ,"A10C_whoami-b",false};
   {"A-10C_PAINT_1-c", 0 ,"A10C_whoami-c",false};
   {"A-10C_PAINT_1-d", 0 ,"A10C_whoami-d",false};
   {"A-10C_PAINT_1-e", 0 ,"A10C_whoami-e",false};
   {"A-10C_PAINT_1-f", 0 ,"A10C_whoami-f",false};
   {"A-10C_PAINT_1-g", 0 ,"A10C_whoami-g",false};
   {"A-10C_PAINT_1-h", 0 ,"A10C_whoami-h",false};
   {"A-10C_PAINT_1-i", 0 ,"A10C_whoami-i",false};
   {"A-10C_PAINT_1-j", 0 ,"A10C_whoami-j",false};
   {"A-10C_PAINT_1-k", 0 ,"A10C_whoami-k",false};
   {"A-10C_PAINT_1-L", 0 ,"A10C_whoami-L",false};
   {"A-10_Number", 0 ,"empty",true};
   {"A-10_Number_Noze_F", 0 ,"empty",true};
   {"A-10_Number_Noze_T", 0 ,"empty",true};
   {"A-10_Number_Wheel", 0 ,"empty",true};

}
name = "Mod: Who am I?"
countries = {"USA", "RUS", "UK", "UKR", "GRG", "RSO"}

The skin mostly works, but a few areas are without skin and end up with the "default orange" color, like this:

 

 

 

A couple other areas aren't textured right; the inside of the airbrakes are also orange, as is the little antenna (?) near the tip of the right wing. I've tried several things to try and fix this, from making the file names .bmp.dds and adding ".bmp" to the filename described in the lua to straight-up using bmp textures. None of it seems to get rid of that orange color. Any ideas what I'm doing wrong?
