Rh at low temperatures can be very difficult to maintain. But trust in your beads. It can be difficult, most of us have been through this before. In time you will learn to trust the way your cigars are smoking more than anything else.
If they smoke and draw well, you are doing good.
One thing I did not see is if you calibrated your hygrometer using the salt test.
It could be your hygro is reading low. No problem, just remember to add or subtract the % of deviation. The more smokes you add will also help maintain a constant Rh.
