You need to put these in both skip_services and skip_outbound_services.

Yeah, I know, this isn't intuitive :-(.  The configuration for scan.bro
is pretty much a mess, and we have a rewrite of it pending, but haven't
managed to get it fully together yet.  Sorry about that ...

Right, the summary is decoupled here.  Jason or Roger will need to chime
in here, as they're the ones who develop/maintain site-report.pl.

Again, sorry about the confusion ...
