Html code interpreted

Hello,

I want to add some Html code into my FAQS but I don’t manage to get things working.
My code appears well when I directly access my FAQ page but not when using The FAQ list with toggl option.
Both pages are :
https://netoxygen.ch/faqs/comment-choisir-la-version-de-php-utilisee-pour-mon-site/
And
https://netoxygen.ch/support/faqs/ (toggl Comment choisir la version de PHP utilisée pour mon site?)

Thanks for your help

The page I need help with: [log in to see the link]
