I am hoping you have a small hygrometer in the jar with them. You want to get the RH in there to 60-65% for at least a week or longer if you can. Slower is better in this curing stage, and the dehumidifier was a probably a bit too efficient. Lettuce, or my favorite, a cutting from one of my other flowering or even vegging plants, put into the jar will add a lot of humidity back into over dried product, but it won't be the same as if you had slow dried it. Do what you must though, and get it to 60-65% humidity asap, and keep it there as long as you can. It will be worth the trouble.
