Unwanted formatting text

[WarrenD602]

Why is the unwanted text (circled) appearing in my emails?  How do I eliminate it?

Hello @WarrenD602 ,

This is CSS coding is forcibly added to emails, typically by a Chrome or Edge browser extension called Microsoft Editor Spelling and Grammar Checker (though other incompatible extensions may also cause the issue). I'd advise disabling the extension or using Incognito mode to make a copy of the email, and then edit the copy. Please note that any further editing of the email with the extension enabled may re-add the code, and should be avoided.

That was absolutely the problem!  Thank you!
