Poro Ward Skin Vision Ward Showing Up As Battlecast Ward

I have the Poro Ward skin. When I place normally purchased Vision Wards, the ward shows the Poro Ward skin (which I have activated). When I upgrade my Vision Trinket to a Greater Vision Totem (Trinket), those pink wards show a battlecast ward instead of my normal Poro Ward skin. I also know this is bugged because I don't own the Battlecast ward skin.
