Dear Mike,
Thank you for using the AR-DV1 and for taking the time in sharing your concern with us.
Good job into finding this bug! We are sorry for the inconvenience caused. Let us run some tests and fix this little problem soon. In the meantime you can conveniently revert to 1702 if 1710C is too much trouble, until we find a fix.
Thank you for your patience.
Best regards / Mit freundlichen Gruessen / Cordialement,
