Support System styles not loading


I installed the Support system plugin (v2.2.1).
There are 2 things I need to solve:
1 - The Front End settings are not showing the pages selector (not a problem at all)
2 - The Faq and Support pages crated are not loading the Foundation styles nor the support system styles (grid in primis)

You can see in the screenshots that I checked the 'Use support System Styles' option and the resulting FAQ page view.

Can you help me?
Thank you
