First of all I have to say Nice Avatar! Hook 'em horns!!
Okay now down to business. My first question would be how accurate do you think those beads are and are they completely saturated? Do you have a hygrometer in there with the sticks?
That sounds like over humidification to me so I would double check that the beads are not completely wet and that they can absorb moisture. It is possible that you got the sticks from a B&M that keeps them wet and when you put them in your container your beads got full and can't absorb any more moisture. If that is the case then just use a blow dryer on them and dry about 30-50% of the moisture out...
