I was trying out track motion in a picture in picture situation & used the shadow function. Somehow I managed to get the shadow offset from the picture by an ever increasing amount. I went back to track motion & saw that the shadow can be keyframed seperately from the main picture. I tried deleting the keyframes from the shadow & go rid of all of them excect for one. I'm still getting the shadow traveling independantly of the picture. How do I fix this?
