Unchecking "Show sharing buttons" does not work

What’s the URL?

The floating bar shouldn’t show on that page if you unchecked “Show sharing buttons” in the page editor.

Does the site have a cache that needs to be purged for the change to take effect?

Until you find out why the “Show sharing buttons” toggle isn’t working on your site, you can hide the floating bar on that page using a line of Additional CSS code:
body.page-id-1099 .a2a_floating_style { display: none !important; }
