Can’t edit text in preview

Hello, I’m trying to edit the Customizr theme through personalization page, and I can edit the text of buttons but not the text of “Text Editor module”. At the left bar, in section “Content”, i appears 2 buttons named “Edit” and “Hide editor” that doesn’t response at any action.

The WordPress, plugins and themes are up to date, and I’ve disable all the other plug-ins also, but the problem remains.
