Endnote stopped working as it should

HI all in the community,

Endnote was set in APA 6th and reliably providing correct intext referencing e.g. (Hardey, 2013), complete with hyperlink and editability.  I loaded a new reference and since then it has been giving this {Griffith, 2010 #224} style when Im inserting intext referencing.  No idea what I have done to cause this, the # denotes the number of the reference in the master list.  Any advice and insights would be appreciated. 

Thanks
