Skin shop packs not giving skins

i am having issues with the skin shop plugin on some servers where it gives the pack but then when i open them it gives no skin to add to the collection only on about two of my servers the rest are fine pretty much the same plugins on most of them. on the 2 that they don't appear on i copy my skins from the data folder to the problem ones and it shows my skins from the others i collected.

It might just be image library taking awile will update if it ever loads.
