[Rank counting as normal]

I have played the game for some time now and this is the first time this has happened to me. The past three games I've played in Rank two were wins and they counted as a Normal game. The third, and last game, was a lose and the game counted it as Ranked. I did not do anything different than I did queuing up for the other two games. Any help would be appreciated because I was fairly upsetting when I was doing good in my games I received no LP, but the one game I lost I lose LP.
