Use any skin glitch in new ranked draft?

To start this off, I'm on my phone as of now so if there are typos please forgive me.

To start this story offi decided to play some of the new ranked draft pick with two of my friends. When I got on I got jungle and picked jax and I had no skins for him. Next game I got jungle again and thought I would go as him again. I was trying to maneuver around the skins part after I selected and got confused. After the timer was over I have no idea what I did maybe a clicked on something weird but we got into the loading screen and my friend asked " wait you have jaximus? " and I quickly replied with no but I looked and that skin was equipped. My friend said he gave me that skin for my birthday but I never got a notification about that. After that game we had to go and I clicked on the gifted tab and I never received a jax skin from anyone or bought it. I clicked on the jax skins tab and looked and I didn't own it. So I have no idea what I just did but I may have found a bug where you get any skin for free? I don't know leave your comments below
