Keybindings Glitch?

This is an occasional glitch that happens to me on the regular, it's reached the point that I've lost PVP matches because of it. I usually relog and the issue goes away, but now, that's no longer a fix. I've done everything, from relogging, reverted my settings during the match as default, then setting them back to quickcast. I'm not able to use any skillshots using my keyboard (I can only click on a skillshot and click again to cast it), I can't use items, recall, or place wards without using my mouse.

Todays match history: Aram (Keybindings worked) Aram (Keybindings worked) Custom (Keybindings didn't work, relogged, then they worked) Dominion (Keybindings didn't work, relogged twice, never fixed the issue) Bots (Keybindings didn't work, relogged, never fixed the issue)

I'm tired of having to be afraid of playing a match and my keybindings not work.

• My keyboard is not the issue, I can type in chat just fine *

Please help, this is becoming tiring. :^(
