I passed checking Mr. SK Jena, where SK is actually the abbr of first two names and 'Jena' a surname. However, It termed SK as tag 'And', instead of 'Given Name' and also marked 'Jena' as 'Given Name' instead of 'Surname'. However, this is not the case when I passed only 'SK Jena', It was able to identify both name and surname correctly.
