[Networker] mminfo results: with and without -q 'level=full'

Dear All,
 
can you explain the mminfo results I am getting:
 
I definitely have full savesets (see the 1st mminfo command), but when I
add level=full to my mminfo statement I get no savesets back (see 2nd
mminfo)...
 
Thank you for your help,
Aleksandr
