Queued for draft, game results show ranked game. Wtf ?

Hello summoners, here is a little story:

I just went into a draft game to train adc with a support premade, not going to talk about the game itself, all in all, we lost. Then the results show up, and it shows ranked, at first I'm like ''- oh maybe I queued for ranked by mistake" then I clik on play, and see that the last game mode I used was normal draft, do any of you guys noticed this kind of bug with the dynamic queue ?

I am really annoyed right now, I wish someone in riot's staff could delete this ''ranked'' game since it wasn't supposed to be one, I'm usually not playing more than 20 ranked games per season, s every single of them count for me.
