#H5P "course presentation" : quotes are converted to html entities

Hello, I have a problem when I create a "single choice question" in an interactive content : "course presentation" : quotes ( ' ) are converted to & #039; ( http://i.imgur.com/JxkfeN4.jpg</a" title="screenshot">screenshot ) I googled for hours and found topics related to CKEditor (editing the settings.js file) or PHP configuration... but the problem still remains :-/ Has anyone faced this problem please?
