Having trouble with cooldown resets

Here's a link to some pics of the code for anyone who doesn't want to check in overwatch.

So, I'm trying to make the interact key work like an ability and have it slow down time for the players. I have it working (somewhat) but for some reason when the cooldown resets, it takes 1 extra second off and breaks the ability. I don't really have any previous coding experience so I'm not 100% sure why it's breaking. Any help is appreciated, even if it means scrapping it all and redoing.
