Raise them off the ground ever so slightly. They are most likely intersecting with the ground plane. ;) Maybe add some caustics for the hell of it? :D

I knew it was something simple but I did not get it, thanks.
As long as the text (Slow) is next to the caustic enable switch, I usually try  to avoid using caustics :)
