Cloth Diapering Question: Pocket Diapers making daughter's bottom stink?

Just switched over to Fuzzi Bunz full-time, and now I'm having an odd issue that I can't seem to find any info on. My daughter's butt kinda smells. I bathe her nightly, the diapers themselves do not stink, but she still has a bit of a funk to her-- even after bath. Anyone else have this problem? I'm assuming it's from being in PUL and fleece all day. Otherwise, I really love these diapers and have no other issues. Any suggestions? Oh, and she is 18 months old and has never really had this issue before. And, like I said, the diapers themselves do not stink or have any ammonia build-up.
