FCP 7 render/export darker

Hello,

Recently I have noticed that everytime I render a clip or sequence for color correction, after the render is complete the clip readjusts back to the original color. However, if I double click clip and it opens it in the Viewer the color temp looks correct to how I corrected it to be. Is this due to the fact there was an update for my graphics card recently and I updated it? Im so confused.
