When you are in the skins menu and previewing the skins the cell wall (status?) is taken into consideration.

for example: with the green skin... previewing blue cell wall IN PREVIEW doesn't show the white cell lines until you select it and let it restart... then

with the blue cell wall skin -> previewing anything else still shows the cell white lines when they shouldn't be there.

so basically the skin preview is changing the cell wall lines for the preview.

hope that makes sense.

NICE DASH BTW!
