Hello! I'm not sure if it is the correct thread to report the problems, if not please re-direct me.
I've got 2 new Kobo Aura One readers, both have been updated with 4.5.9587 and both have the same problems (described below).
I have 2 types of kepub books in KA1 - "downloaded" (from Kobo store) and "imported" (through Calibre).
If I've been last reading one of "downloaded" books than it will appear on the primary position on Home screen and it's cover will be shown in Sleep mode.
If I've been last reading one of "imported" books than:
- it doesn't appear on the Home screen at all;
- the latest read "downloaded" book is still on the primary position on the Home screen;
- the cover of the latest read "downloaded" book is shown in Sleep mode.
It doesn't matter how many of "imported" books I've been reading - none of these book will appear on the Home screen. These read "imported" books are not present in "My books/All" recent list either.

The situation changes only if I delete all "downloaded" books from KA1. In this case the cover of the "imported" book read at the moment will be shown in Sleep mode but on the Home screen the primary position is empty ("No book is being read").

All other parts of the Home screen always remain unchanged (Even in case of reading of several "downloaded" books - just the latest read book is on the primary position, all other earlier read books are not shown on the Home screen).

On the earlier FW 4.3.9084 everything related to the topic above worked perfectly.
