A couple things to think about:

1. RH meter calibration. 68% on the meter is within tolerances for most meters even if the true RH is 65%. It may just be that for your meter, you have to subtract about 3% (at this time, next calibration, it may change)

2. 65% beads can really be anything from about 62-68%. If the beads are not showing as full of moisture, then you can assume that the humidity isn't really much more than about 1/2% or so above their set point.

3. If the sticks are smoking well, don't mess with it. Well smoking sticks are what you are looking for and it is way more important to just note that, for your tastes and this specific meter, when it reads 68% you are happy. Don't mess with happy. I know you know this, I just like hearing myself talk.

4. If you have a spot that is above on RH (I base it on bead condition normally), move some drier beads there and move the wetter beads to another location. This type of rotation can be done as often as needed without harm.

Vertical is a real pain in terms of keeping RH controlled. I'm finding that with a 5.5' tall humidor myself. I wish you all the best.
