I have a similar, somewhat random, problem, and I have not figured out what triggers it. It usually happens when I click on the rating column for a book, select a rating, then click on the menu icon for the Reading List plugin to select either "Add this book to list" or "Remove this book from list." Most of the time, my newly-selected rating will disappear. I have gotten used to selecting my rating, moving to a different row, then reselecting the original row before doing anything else with it. It doesn't always happen, but it happens enough that I always click on another row after selecting a rating, just to make sure it sticks.
