Hi there,
By incorrect position, you meant you are trying to drop the source in an incorrect Target and then trying to move it to the correct target?
Enabling 'Send Drag source to original position’ option sends back the source to its original position if it is dropped anywhere outside of a target. If this option is off, then you can drag and place the source anywhere on the slide.
Enabling 'Redrag the dropped source' option allows you to redrag and drop an already dropped source from one target to another.
Thanks,
Nimmy Sukumaran.
