Problem with Responsive Image

My new website is about to be launched but when I check out the layout on my ipad and mobile device it looks like the image below although fine when viewed on my MAC. How do I remove the ‘text box’ which appears on every page?

Hello there,

I hope you are doing well today.

That text-box should only appear when you are logged in as the admin.
Could you please provide a link to your website so that I can inspect it?

Best Regards,

The website isn’t launched yet ? I log into the draft website with my username and password. Do I need to check a box?

Hello there,

When you are not logged into the WordPress admin panel, are you able to see the text box on the website ?
