PRS-T1 Wrong cover image in menu

[uofabigd]

Is anyone else having this problem? And perhaps anyone know how to fix it?

In the menus of my reader some of my books (<10%) show the wrong image as a book cover, showing instead the cover of another book in my library. When I open the book, and turn off the reader, it shows the correct book cover as my screen saver, but still shows the wrong cover in the currently reading menu, and all other menus. This doesn't affect the readability at all, but it is pretty annoying. The only way I have been able to fix this was to delete the book and re-load it. I load all books through calibre. Thanks for your help!
