Hello afgb1977,

Thank you for reaching out! After further investigation I've gone ahead and removed the alt_name=Corona Island tag from the feature (https://www.openstreetmap.org/changeset/160547296). I apologize for any confusion or inaccuracies from the alt_name tag being added onto the feature. Thank you again for reaching out to us, and if you have anymore questions, comments, or concerns, please do not hesitate to contact us. Thank you!
