Issues with lights and DCC Functions

[Smerrfy]

I need help!!!!

I installed headlights, tail lights and cab lights in a Lima Class 60 loco.

The cab lights are connected to the Green Aux 1 F3 wire and are controlled by Button 1.

The headlights and tail lights are directional and connected to the white and yellow wires - controlled by Button 10.

The cab lights work well.

The headlights and tail lights also work - BUT my problem is that when I turn on the head and tail lights the Cabin lights also come on. If I push Button 1 to turn the Cabin lights off - the cabin lights stay on but the head and tail lights go out.

I have checked and re-checked my wiring and there is no cross connection between the lights other than to the common blue wire.

I am guessing it has to be something to do with the CV addresses (maybe?).

Any help would be greatly appreciated.

This is obviously hot a Hornby decoder, nor a Hornby controller, so to help we need to know what these are.

 

Some decoders can link functions so that one can operate abother and that is what seems to be happening here.

Come back with the info requested and we will help some more.
