I'm not sure exactly which error is being reported to you, but I did look at the profile and wondered if this could be related to the error: Verna Ridgewell married to Alden Harry McBurnie. "Ridgewell" is showing up as her last name of birth -- which is correct -- but McBurnie probably should be listed as her "current last name" in the spot above where you fill in individual information.
If she married more than once, then the current last name should show her last name at the time of her death, (and then McBurnie would be in "other last names").
If the error was triggered by a difference between her profile and Findagrave, it might have been caused by the difference in names.
Again, I'm not sure if that's what triggered the error you are seeing, but it is one possibility. Try changing the current last name from Ridgewell to McBurnie (if that's accurate), and see if it keeps the error from returning.
