referencing error


I am using endnote ‘numbered’ style for referencing. Just now i faced a problem while making citation. There is an error while i cite the paper, its not giving the normal way but showing like this {Xi-Guang Han, 2009 #293} instead of numbered format ‘[40]’. I tried to reopen the document and check but its giving the same problem. Could any one help me out? 

Many thanks
