Visible Java Script embedded in email

[MicaelaL23]

I keep getting these visible messages embedded in my email when I send it out.  It is very distracting and takes away from the style and messaging.  What does it mean and how do I get rid of it?  I can't see it in the editor, but it is visible in the preview and sent email.

@media print { .ms-editor-squiggler { display:none !important; } } .ms-editor-squiggler { all: initial; display: block !important; height: 0px !important; width: 0px !important; }

Hi @MicaelaL23. Do you happen to be using an extension called "Microsoft Editor Spelling and Grammar Checker"? We've seen a few instances of this code appearing when the extension is turned on. When it is turned off, the code will not appear in preview and a test email. You will need to make a copy of the affected email once it is turned off and continue to make edits there.
