You are working
, but in the future (all you peeps):
Please include the bottom status line, it contains useful information to helpers.
The one I included tells us :
There is a filter/VL that restricts the view
There is only 1 book selected <<<
look at this often, other selections may be off-screen, and you may NOT want to do the next action on all of them
The last tells us the total KNOWN (to calibre) size count of the Library we are working with
