Profane Armor not in Wardrobe Storage.
It would not be a bug. If you removed, destroyed, lost, etc. any armor, purchased or not, before the advent of the Wardrobe, it would not be included in the Wardrobe.

Please note that skins or partials skins that you previously purchased but which you no longer possess will not be unlocked on your account. The Guild Wars 2 Support Team cannot unlock skins that fall into this category.
Good luck.
