Logo Light Switch on Project Airbus A380

I wasn't really sure where to post this. My apologies if this is not the correct forum.

I have downloaded the Project Airbus A380-800. THE PA380 was designed for FS2004 apparently, but has been ported over to work in FSX. The FSX version does have a VC and utilizes a Tom Ruth A340 Overhead display in the VC. It uses the default FSX A321 overhead in the 2D view, so you are missing 2 generator switches and two bleed air switches, but that is beside the point as I try to use the VC view whenever possible.

Using the VC there are toggle switches for the Landing, Taxi, Beacon, Wing, Strobe, Nav, and NAV&Logo lights. These all work with the exception of the NAV&Logo switch. The vertical fin/tail texture is A380_1_T.bmp and there is a corresponding light splash bitmap labeled A380_1_L.bmp.

Unfortunately, toggling the NAV&Logo switch does not generate a light effect on the vertical fin (nor does it turn on or turn off the NAV Lights, but the NAV toggle does this just fine). Toggling NAV&Logo appears to do nothing and acts as if it is a dummy switch for appearance only.

Does anyone know if it would be possible to make this toggle work or add a new toggle specifically for the Logo light? I've looked at the xml code for the Tom Ruth Overhead and found two sections that mention Logo, but do not really understand what the code is trying to do. Both entries only reference the bitmap for the switch, not the action the switch generates, but in all honesty, I know very little about xml gauges.
