How long have you had the cigars in there and how full is the humidor? Though it will take time for them to absorb the humidity. Does your humidor have a tray or wooden dividers? You can let these sit out to dry and then put them back in to absorb the extra humidity.

Also what kind of hydrometer are you using?

It can drive you crazy, I know. The same happened to me when I setup my humidor and first cooler. Just be patient.
