Safari Duplicating Bookmarks

Since turning on iCloud, I have this issue where Safari 8.0.3 (10600.3.18) keeps duplicating book marks and bookmark folders. I now have about 7 copies of each bookmark. (Same issue extending to Contacts and files)

I have attempted to turn off and re-enable iCloud but the problem keeps compounding. I've seen older post as far back as 2009 on this but no real resolutions to speak of.

Help appreciated!
