The category is not displayed in the list by authors
In other lists, and inside, when I go into the book itself, the category will be displayed.
I reviewed it, where possible in the settings, it was set to "Display category"

I fixed the bug, I will publish a new release as soon as possibile.
If you want solve it early try to apply this fix.

from:
$query->select('c.title AS category_title, c.alias AS category_alias, c.access AS category_access');
to:
$query->select('c.title AS cattitle, c.alias AS category_alias, c.access AS category_access');
Super! It worked
