unintentional dodging while duo

So i was just in a duo Q for ranked and while my partner got the alert for lobby i did not, but the music changed and when it was "my turn" to pick my champion the client still popped up as if i was in lobby even though i was currently on the store minimized while on facebook and not actually in a game lobby... i lost LP for this and had a timer as if i had dodged a game...
