Hello @StephenieB59 ,
When I checked your your landing pages that you've created, they all looked the same between the editors, previews, and live versions. You may want to check your browser's settings to see if you have any rules in place for overwriting font types, or anything else that would change a site's set styles.
Otherwise, I'd advise calling general support so they can continue to troubleshoot your issue live, and collect screencaps and exact examples of your described issue.
