Press the green flag, space, or the button with the arrow to generate. There are up to 3 kits. I'm sorry, there's a glitch with the names where sometimes a name won't show up, or it'll appear when there isn't a kit there. I've tried to fix it, but apparently I only managed to reduce the likelihood. I'll try (and hopefully succeed) to fix it in the future, and I hope this doesn't happen to you. My sincerest apologies if it does.
