The beads you have may (and I stress may) be okay. But, my understanding is optimally when you hydrate your beads you should aim for 1/2 opaque and 1/2 white......better yet, if your running high now, dry them completely out and put them in dry (all white). If your humidor is higher than the bead's preset RH, they should pull the moisture to them.
I'm not a bead expert, but that's my understanding of how they work. Here's a post by someone who knows a lot more about beads than me.

And definitely calibrate your hygrometer just to be sure! Here's a post by the same member...Mark's a good guy.

BTW - both of the links are stickies. Read up on them and a lot of questions may already be answered.
