I am having a similar problem. I have 9 Resource Lists visible on the left hand side, and when I click "add to List" under "Edit Book" on an item in my book library it only shows me 4 to choose from. If I go through and pretend to edit a Resource List title, it will then show up on the next book I look at under "edit book", but it bumps other entries off. I can never see all 9 resource lists as options to choose.
Any one fix this yet?
