Not showing me entire pre-chat in blind

I like to play Blind a lot, as it's fast to get into games and I am pretty much guaranteed to play who I want to (Since no one can ban champions) But for my past 2 games I've been getting a glitch where I can't see some pre-chat messages. (What this means is that I can't see what some people have claimed) This glitch has lead me to be forced into weird roles, the first time I ended up Kayn Top, and the second time I ended up Fiora support (Which we somehow won) I'd just really like this to be fixed, because until it is, I can't really play Blind.
