Authors citation

1.Found one author always with citation Z.N. Kain et al. instead of Kain et. al. 

  1. already turn on omit repeated authors in the template, but still have the citation like these:

     Z. N. Kain et al., 2007; Z. N Kain et al.,2000; Li & Lopez, 2008; Li et al., 2007), any help?

There is a subtle difference between Z. N. and Z. N that Endnote interprets as making them two different authors.  copy and past one author selected from one of the records and replace the second one and that will fix it.
