Warning 313: Missing mothers DNA confirmation
The "Confirmed with DNA" checkbox requires a very specific statement in the Sources section showing who took the tests, how they are related to the person in the profile, and what their exact DNA match is. If that statement is missing you'll get the error message. You can just change "Confirmed with DNA" to "Confident" and clear the error or post the required DNA statement. Here's a link to the Help page that explains the correct wording: Help:DNA Confirmation (wikitree.com)
