Normal Draft getting mixed with ranked queues [Client]

This happened probably somewhere between the time the ranked stats were reset and maybe a day later, so i have a ranked ban since the new system was introduced, probably it saw some bad behavior from earlier games and decided to give me 45 ranked game ban. So i played some games of normal draft, i have 15 games left at the 15th game i play ADC Draven. Luckily i won the game, but after i went to see my match history i see that the game i played was recorded as a ranked game. This happened twice once i lost without even knowing i was playing a ranked game, and the same 2nd time. So i am interested in how this happened, for example i have ranked ban i cannot select the ''match me with teammates'' button but there are moments when i am allowed to pres it but after i press it it shows a window which reads ''Due to recent bad behavior on this account ranked solo/duo queue has been disabled on this account for (number of normal draft games) games. So after that i close the window and select the normal draft queue, we start the game, finish it then i look at my match history and there is the ranked game, but i was sure that i selected the normal draft gamemode. So this might be a temporary bug but i am not sure so you might wanna see to this and i hope it gets fixed.
