autodiscovery job create without target

[meldrone]

hi,
since upgrade my 5.2 on last 5.3, all new job i create is made without target in command line
for example i make new job with plage ip 172.42.2.0/24 and clic on "add target"
display well the plage ip with one "delete this target" red bouton
but when i clic on "begin auto-discovery job", the job run less than 1 second and the command line display is
Executing nmap via: sudo /usr/bin/nmap --max-rtt-timeout 100ms --max-retries 0 -sS -O -A -v -oX /tmp/198-nmap.xml

as if target don't push on the script
