Duplicating Webpages - Previews old cover photo

[Nakara30536200o56x]

I duplicate a webpage each week to create a newsletter. Since new.express duplicated webpages hold on to the original cover photo and shows it when previewing in "Your Stuff" and when sharing link via text message

I use webpages for a newsletter as well. I finally got the old webpage to conver properly, but I can't preview the webpage at all. Nothing loads.
