Content is missing from my site editor, but if you visit my website it still appears. Why can't I see it?

I just logged in to the Squarespace editor to work on a website I'm designing for a client. I am the only person with access to this site at the moment. For some reason, two of the pages are suddenly missing content. I most definitely did not delete the content! If I go to the site from another device that isn't logged into the Squarespace editor (my laptop, my iphone), and refresh the browser, I still see the content there. But for whatever reason, it's missing from within my editor.  I'm using a Google Chrome browser. Is this a known issue?

Oddly, about 15 minutes after I posted this, the issue resolved itself. I don't know how or why, but I'll take it. However, I have found other posts in the forum where a very similar thing happened to other users. Worth looking into, Squarespace. Thanks.
