Window file creating a new skin rather than altering the window

[Shaxx's 3rd left rib bone]

I'm having an issue whereby the the window file that i've named alt_pWINDOW (alt_p being my main livery name) just creates a new skin file rather than changing the windows of the livery, it's attatched in the .mas file and i've setting it to read only didn't help.

I've attatched below screenshots of my files, the contents of the MAS file, the skin I want changed having not changed and finally the weird window file skin.

Any help is greatly welcomed.

Just use the mas tool to open the mod team file or upgrade file check the name for the window files used. Sometime it can be windshieldin. windshield out, windows. cheers
