Ok this one should work with the standard nmap.nasl plugin...

That actually prove that the plugin was started, but it might have
aborted. In this case you should see something in the dump. Otherwise
(if the plugin succeeded) an entry like
Success/188.8.131.52.4.1.256184.108.40.20659=1 should be set. Can you check

All these entries look good. I am unable to reproduce the problem.
I've tried with several versions of nmap and things just work as
expected. Are you running the scanner as root? Do you use custom
parameters for the nmap plugin?

This is normal behavior. These ones are NSE wrappers for the new
nmap_net subsystem and use network wide scanning.
