Night Strobe is not functioning.

Helicopter is running and the day time top and bottom strobes work but the red strobes for night flying are not working. I have cycled the switches, changed the strobe from top to bottom to both, turned the Nav lights from Norm to IR(shouldn't affect it), changed Nav lights from steady to flash(again should not affect it), and went from Bright to Dim for the Nav lights. Also seems to be some issue with the rotors at night on the MH-60T when viewed from above both the main and tail rotor disappears. I've only noticed on the Tango because I haven't done a night flight with the other two yet. It seems to be an alpha layer priority issue, and I am not sure it is the helicopter or the scenery I was using(Verticalsim St.Pete/Clearwater Airport(KPIE))with the latest update from Contrail. Great modeling on the aircraft, the textures are fantastic, and Echo19 has done it again with the sounds and I see that y'all fixed the upsweep on the main rotor blades.
