I do not know if this problem has ever happened with anyone else. But, whenever I add a new citation or refresh references from Mendeley tool in my Microsoft Office 10, the references will flush right. I have to roll down to the references and flush them back left-to-right. It annoys me. I did not try to reinstall Mendeley or to replace the Microsoft Office I am using. I thought if I can fix the problem without reinstalling, then that would be great.
