I have a small clip on the timeline that was cut from a larger clip in the Media Bin. I applied an effect to that clip on the timeline, but it changed every instance, and every clip cut from the original. I only wanted the effect to apply to the one clip that I applied it to. 
Am I doing it wrong, or is this a bug?
