jen, do you have 8 frames or 9 frames in that box?
the reason you have the waxed mess between 3 and 4 is because the frames are not spaced evenly. i use 9 frames in a 10 frame langstroth deep, i don't do this for mite drop, but for other reasons, ventilation, and ease of removing frames, examination etc. i space them evenly across. do as apis said to pry, remove them, and clean them up, then ensure that your frames are spaced evenly. or you can do as crofter said with an extra box.
also, if you use or start out with undrawn foundation, you must start with 10 frames, as soon as these are all fully drawn, remove one frame, space evenly, so that you can go to 9 frames.
