Dear Riot, Please fix 3v3 Ranked - Can't invite

After a Win I am unable to invite the same people again, it puts me in the room as if I had invited them already but I'm unable to start and they cannot join the game as I cannot invite them because they're "already there" but there aren't

My team is also unable to invite, as it does the same thing to them.

Currently I need to restart my client every time to be able to re-invite them. Please fix!
