I added a chroma key effect to one of my videos on a track but ever since then, it chroma keyed the entire project. I attached a photo. You can see clearly that the image was originally green and it has no chroma key effect on it (only pan and crop which is already on by default). This chroma key glitch didn't even make the background transparent, though. It just made it black so in order to get rid of the black background, I'd have to chroma key again but with black which is not as effective as using bright green.

does anyone know a fix to this or how to prevent it?
