humidor won't rise above 50, how do i fix that?

[ggiese]

recently bought a used table top style glass top 100 stick humidor off an acquaintance. it had been seasoned and is perfect condition. i tested the hygrometer with the salt test, read as perfect. it came with a couple triangle shaped bars full of water activated gel beads as well as the standard green foam 'block' that mounts inside the case....
o
my issue, as stated in the title, is that no matter what i do, i can not get the humidity to rise above 50. i tried a gel bead bar, 50. got some 'cigar juice' solution, soaked the foam bar, 50. set a bowl of distilled water inside. 50. put it in a very warm, dark closet, 50. set it on a table away from windows, 50. originally i only had about 10 sticks in it, added another 30, still reads 50. nothing i seem to do raises or lowers it any. only thing i have not tried is using both bars and the block, but that seems excessive.

any suggestions on things i could try or possible causes?

thank you, appreciate the advice.
