My F key is not working

Hello, After a year-long break I decided to reinstall LoL to play some games with my friends. I've played about 7 games now and I can't get my F key (secondary summoner spell) to work. I've tried putting either exhaust or ignite on it, and it just won't proc like it used to in normal games. It works fine in practice games however. Can anyone help me with this issue? I've looked through the settings, tried different things and I can't figure out what's going wrong. I'm definitely close enough to enemy champions to use the summoner spell and have also tried using Shift+F, which also doesn't work. It's quite annoying to play handicapped like this. Thank you in advance, Caulifl0wer EDIT: I solved the issue by putting flash on F and Exhaust on D, somehow that works out.
