Touch Sleep/Power off Covers using MicroSD card 2.5.2 bug?

[VirgoGirl]

Hello, again.

I managed to update the Kobo Touch (n905) to 2.5.2 (checked the device, firmware correct). I had about 55 sideloaded books on the device itself from when I had to reset to factory firmware. Those were still on the Kobo HD when I upgraded, they render fine on the Home page "carousel" and when I put the Kobo into sleep/power off mode.

I reinserted my SD card and added 4 books to it in order to test the device. Those 4 books never move off or around the home page "carousel" - when I open a different book on the device itself or one of the other 3 on the card, the covers don't come off the "carousel" to make space for the newly accessed books nor do they move from their place, around the "carousel" if I open a different book from those 5 displayed (4 sd card books and the current book I am reading that's on the device itself).

When I created shelves on the device, those 4 books did not display their covers on the "add books" list, but DID/DO display them on the normal "Library" mode or when viewed on the shelf itself.

If I open one of those 4 SD card books, put the KT to sleep/power off, the book cover says the title of the book and the format but does not display the book cover image. Ex:
The Hobbit
by JRR Tolkien
epub format

If I then open a book that is on the KT itself, put it to sleep/power off, I still get the book cover I previously looked at on the SD card. The KT will open to the book I am reading when I power it on - either on the card or on the reader - but it displays the previous SD card book cover unless that book was "finished".

It appears to me - who admittedly knows NOTHING - that the firmware now makes you choose to either exclusively use a microSD card or the KT itself. Why the SD card covers are not showing up during shelf creation or why they don't move on the "carousel", I have no idea. I DO know that this is the kind of thing that is making me seriously consider the Sony T2/T3 reader to replace the Kobo (I can't buy a Nook, don't really want one anyway).
