On my site: RobsonOnline.com, I have added some HTML code and made many successful edits. One page has some old code that is now redundant and causes this at the bottom of the page: silent.html 

Using F12 I can see the offending code  Popups 01, 04 & 05:

This offending code is not visible when using: Settings/Advanced/Statistics and Code

so I am unable to delete it.

If I delete it manually using Atom Editor, the page works fine, but the offending code returns when I export the site again using X5.

I am usig version X5 EVO 2021.2.8

Can anyone help please?
