If your already read list hasn't been updated on the first pass (which finished yesterday), it may mean you've just been missed and will be updated on the second pass (which is around now). That being said, Non-rated manga will take a little longer as the focus is on rated manga right now.
This is the FAQ, I highly recommend reading them.
