Endnote 8 not updating references


I recently created a new group in my endnote library. I had to sync my references as i wanted to share with a colleague. I have references for several manuscripts in my library. After syncing i am unable to correctly add references to the other documents i am working on. When i add references they are not formatted and they dont realign with the other citations. I have tried updating citations and bibliography but this does not seem to work. I would be most grateful for any suggestions on how to oversome this. Thanks.
