Panels_data are visible

Hello
I’ just installed Page Builder. Everything seems to work fine except that, when I display the article, there is what I want (column, texte, etc…) but also all this : panels_data: a:3: and many line of code describing everything I wanted PageBuilder to do. It is at the beginning of the article. At the end of all this texte, there are my columns etc.
What can I do to avoid to have al this data?
My website is not online yet, but if you really need to see, let me know and I’ll put it on line for a moment.
I’m using a template : Crush.
thank you, regards Florence
