Witcher Sign Question (possible spoiler)

I've been playing for a few hours and am about to go into the Salamandra's Highout but for some reason, my two signs aren't on the lef side of my screen anymore. Well, their slots are there, but the colorful signs aren't there and I can't use them by pushing the right mouse button. Do I have to do something to get them back?

Ahh, sorry guys, figured it out, was in a safe zone. No worries.
