Yet, another beads question

I've done as much research as I can in FAQ on this forum and haven't found a reasonable answer to my query. I was hoping someone here has experienced the same problem that I have encountered and could give some advice. Following is the same letter I've sent to the bead company who will remain nameless for the time being.
I recently purchased 1 pound of your 65% humidity beads and have placed them in
all of my humidors/coolers. I have hydrated them with distilled water from a
spray bottle in a 80/20 mixture (80 being clear beads and 20 being opaque
beads). The relative humidity in all of the above humidors and coolers has
actually risen to 71%. I changed the mixture of beads to 50/50 and still no
change in humidity. Am I doing something wrong? I have the proper amount of
beads to cubic inches in all of the humidors/coolers. My RH was almost always
66-69% before beads. How can I remedy this problem?

Thanks in advance people,
Matt
