There’s a limit to what can be done with de-essing …
Paul-L’s high-resolution de-esser is the only tool for Audacity I’ve seen which can help your severe sibilance problem.
Oddly “chaise lounge” doesn’t suffer the excessive sibilance of “sulkily gazed” 
Whatever the arrangement / settings were for “chaise lounge” keep them.
Whatever you did differently for “sulkily gazed” don’t do that again.
