Oh, wow. That seems scary. It's too bad I have to jailbreak in order to continue using Kindle Collections. I will look over the thread provided and hopefully figure it out.
In the mean time for tonight, I'm thinking of trying to keep the Kindle Keyboard updated using Calibre and Kindle Collections, then see if the "Import Collections" function on the Paperwhite will import the collections

properly. I tried that quickly last night and I don't think it worked so well, but I restored the Paperwhite and will try it again right now.
Thanks for your help! I was hoping jailbreaking wouldn't be my only choice.
