[Solitaire1]

I recently purchased a NG4 and came across an issue involving shelves. I created a shelf and put one ebook into it. Then I deleted the ebook and it appeared that shelf also disappeared (but I didn't delete the shelf itself).

However, when I try and create a shelf with the same name it says that the shelf already exists despite there being no shelf with that name. I've tried wiping my Nook and also resetting it, but nothing seems to fix the problem. It's not a crucial issue, but something I'd to get fixed.
