Riot, PLEASE FIX YOUR NEW MATCHMAKING SYSTEM !!!

I entered the new Ranked Draft for the first time, and I selected JUNGLE for BOTH Primary and Secondary. Then it turned into one selection, saying that I had Jungle as Primary since I selected it for the previous 2 selections. When I entered champion select, I ended up as ADC!

What the hell!!

Is this an error? Or is this on purpose? Because if it's on purpose, then I don't see the point in selecting a "Primary" role. I was expecting it to be like Team Builder, where you can select a role and join a team AS the role you selected.

I don't care how long I have to wait just to fill in the role of Jungle on a team. Either fix this bug or PLEASE, just change it to the way Team Builder was with role selection, where you can ACTUALLY get your role upon entering champion select.

It just doesn't make sense altogether how I can just get ADC when I wanted Jungle for both selections.
