Insert "Tab Element" or "Text Block" with extra code in the content area

Hi,
I’m working with enfold 4.8.1. and “Shop Demo” imported.
For exemple, if I insert the “Tab” element in a page, it’s coming with some code in the “Tab Content”, in white color, like
“<p>[av_tab_container initial='1' position='top_tab' boxed='border_tabs' av-desktop-hide='' av-medium-hide='' av-small-hide='' av-mini-hide='' alb_description='' id='' custom_class='' template_class='' av_uid='av-9my2' sc_version='1.0']<br />[av_tab title='Tab 1' av_uid='av-6yji'][/av_tab]<br />[av_tab title='Tab 2' av_uid='av-4t2c'][/av_tab]<br />[/av_tab_container][av_textblock size='' av-medium-font-size='' av-small-font-size='' av-mini-font-size='' font_color='' color='' av-desktop-hide='' av-medium-hide='' av-small-hide='' av-mini-hide='' id='' custom_class='' template_class='' av_uid='av-3v26' sc_version='1.0']<br />This is an example page. It’s different from a blog post because it will stay in one place and will show up in your site navigation (in most themes). Most people start with an About page that introduces them to potential site visitors. It might say something like this:…or something like this:As a new WordPress user, you should go to your dashboard to delete this page and create new pages for your content. Have fun!<br />[/av_textblock]</p>”
If I delete this code, it remains again.
The same happens when I insert a “Text Block”, I get this code, which I can’t clean:

I cleaned all the cache: server, wordpress and browser, but still the problem is alive.
I need to use the Elements (tabs, tex block, etc), Any suggestions would be great!
Thanks in advance.
