Joined Blind Pick, ended up in Ranked game AGAIN

I have always disliked Ranked due to annoying, aggressive people. So I don't play ranked. I always choose Blind Pick. But recently (since Rank Season 6 was released) I have joined a Blind Pick game but end up in a ranked game. This was fixed relatively fast but since this last update (today) I picked Blind pick and ended up in a Ranked game. Luckily, someone backed out so I was able to find a new game. I made sure I didn't make a mistake and pick Ranked Draft pick, but alas, I chose Blind Pick. I searched for a new game and ended up in a Ranked lobby AGAIN. Please fix this!
