Bloodsong seems to have identified this correctly as a non-problem several posts back so let me ask it this way. Which shadow in your rendered image appears to you to be in the wrong place? The one easiest for me to see is the one on the bench from the figure's thigh, and it appears to be correctly cast from the overhead light. If your shadows were generated from a light "dead-on", that one would not be there. I'm afraid I still do not see what makes you think the light sources are actually moving when rendered.
