[stork-users] No leases showing on Stork

Indeed, when I fill a complete name in the search field, it does show
the lease. The problem is that in the "Dashboard" all subnets show "0%
used" and "Addresses 0 / 0 (0% used)", despite that there are active
leases and that the search page does return answers when I fill the name
of a machine.
Did I miss something else?
Thank you,
Roberto
