Defer scripts not deferred

Hello, Gt metrix listed some scripts to be deferred.
https://www.socage.it/wp-content/plugins/revslider/public/assets/js/rs6.min.js (275.9KiB)
https://www.socage.it/wp-content/plugins/revslider/public/assets/js/rbtools.min.js (105.6KiB)
https://www.socage.it/wp-includes/js/jquery/jquery.js (86.8KiB)

I added them in SG Optimizer plugin, in “Defer Render-blocking JS”, but they are not deferred.

Thank you!
