your dry box may need to replace or put in some new silica .That's causing your humudity to get wet (at that rate shown in your pic).you can buy it at some DIY shops or best at photography shops.In fact there's one i bought at a DIY store ,a silica pouch costs around 10$,and you can use it several times,just heat it inside a microwave in case the silica (blue label indicator)turns pink in colour.
The reading is high because this particular box is not air-tight. (I have this box too free gift with dry-cabi) So after a while the humidity will creep up again.
While the plastic finish is not particularly smooth where the o-ring seats, I think it is ok here. However, the hydrometer is attached to the box without any air-tight sealing.
I think this is where moisture leaks back into the box. I would suggest that you remove the 2 screws at the back, remove the hygrometer and then then apply silicone to where it contacts with the box to make it air-tight.

I take out the hygrometer from the free box that came with the digi-cabi and put it in the dry cabi. but now the problem is the reading from the digi-cabi meter is 46 and the drybox meter show 52...Now who to trust???
