lose new paint with "L" key

I finally got through painting my first plane using DXBMP and Corel Photo Shop with a full color pallette.
When looking at the plane in FS 2K Pro from the 'spot plane' view, I loose the front fuselage new paint to the old scheme when using the "L" key alone or in combo with "ctrl" or "shift".
I 'm trying here but what causes that? and is there a layman answer to it?
