Ok Mystery solved. You are using BS2 skins for DCSW. They are compatible however the author who made the skins is referring to in game skins that are part of BS2 and did not include them when he made the package as to save on the size of the download. He included the main camo skin and not the rest of the helicopter. The restof the skins were read directly from BS2 \bazar\world\texture\****.zip file as per the Description.lua file.
In DCSW the naming convention of the skins changed, some stayed the same and some were called something else, hence your missing skins.
If you want to fix this issue, you would need to go line by line in Description.lua file and find the corresponding missing texture file line and find the new name for it in the DCSW
