Why is this? other armor types do not have this issue.

Those are all the grey and white sets which share appearances. Cloth sets have them, but leather and plate do not as I haven't had time to add them yet.

But why are they all visible in the list and selectable? They look identical, it adds a bunch of pages and looks cluttered and "glitchy".
