Custom Cabin Textures at Night (PMDG NGX)

Hello,

I have made custom cabin textures for the NGX, thye show up fine in daylight with the cabin lights at 0% but at night or with the cabin lights on they revert back to the old cabin textures even though I have both cabin and cabin night textures included and have double checked the name and alpha layers of each. I'm using the -700 version. Any Help? Thanks Weston
