Hello, Andymy,
We have conducted a thorough investigation into this matter and have determined that this issue is not related to our theme. It is problem of the WPBakery plugin, and it persists even when a WP default theme is activated on site https://prnt.sc/_uJbfA0HmGBe We regret to inform you that we are unable to assist you in this matter. We recommend using the Backend editor to edit the Home page content – https://prnt.sc/jDPAdrvZmu4A

Kind Regards,
8theme team
