[CLIENT] Match history is not showing all matches

So I was going through my match history in the client and noticed how a couple of games were actually missing. Wanting to make sure it wasn't just me being confused, I checked my Op.gg.

Happens I'm not crazy, my client is not showing all my matches :S

EDIT: Take for reference point my 13/1/8 Jhin game. Look at how games are missing before and after it..
