RIP ward skins

I was going to change my ward skin in pre game lobby when I felt as though something was missing. I thought that I usually had 9 ward skins but I only had 7. I couldn't remember which ward skins I all had so I decided to google a list of them all. As a scrolled through I realized that I was indeed missing some ward skins. Those ward skins being astronaut poro ward and gong ward. I am now sad because the astro poro was my favorite one and the gong ward was the only one I used with Lee Sin. If anyone has any idea why this has happened to me please respond! Thanks
