Cant start queue even if we cover all lanes...

We were a premade of 4 players. We picked our lanes like this : (from left to right) Supp - Bot Bot - Sup Mid - JG Jg - Top

Still, I could not start the queue and had a message saying "Your team must cover a wider variety of positions before queuing up!"

I understand that the way we picked our lanes was not letting anyone who picks bot or support to join our team. That may be the reason why it's not permitted. But if that really is the case, the message should be saying something a little more accurate since we actually were covering the whole map.

Something like : "Every players must pick different sets of positions before queuing up!"

Thanks!
