Publish Sidebar Block Shows Page Preview

Just within that last day or so, I’ve noticed that if I’m working on a page with the SiteOrigin Page Builder in use, the Publish sidebar widget shows a “page preview”, pushing the publish button way down the page.

This does not occur if a page is just using VISUAL or Text in the visual editor.

Using current versions of WordPress, SiteOrigin Page Builder and Disable Gutenberg Plugin.

Thank you in advance for any insight.
