Visual Composer DON’T delete elements

Dear friends. Had somebody this problem?

When we use Visual Composer in bakend editor, we can edit and clone every element, but the DELETE button DOESN’T work (eg: “Delete this column” or “Delete animated numbers”).

We must go to classic mode to delete that element (eg: [kleo_animate_numbers animation="animate-when-almost-visible"]100[/kleo_animate_numbers][/vc_column][vc_column width="1/2"]

Thanks a lot for you answer !!!!
