Drag & Drop object disappear when hits correct target

I have created a drag and drop interaction. The interaction is set for when correct answers are made then it advances to the next slide. The interaction works fine, then when I relocate the drop targets to another area on the slide because I am switching up the design on the slide, one of the drop targets disappears every time it hits the correct target. If I relocate the target back to the original position it still works fine. The size and snap location and everything remains the same. Has anyone ever experienced anything similar to this?
