Buddypress Updates shown Multiple Times

I have a very strange issue, it seems to be computer specific, and not browser specific. On some windows computers, buddypress activity updates are showing multiple times. One status update is shown in the feed 4 times. Both a recently posted update from a user and other users updates that were posted some time ago.

This problem was submitted to me by one of our members after activating Blogs MU, I was not able to replicate it until today on one of our in house Windows computers. It happened on both IE and Chrome so I know it is not a browser issue.
