There is a trac ticket for this and we are aware. I put a suggested fix into BuddyPress trunk but it didn’t seem to work.
So this is a common problem? Does everyone have this issue or is it a plugin. This is really annoying and cluttering up peoples activity streams.
Well the double post should disappear when you refresh the page, does it?? I had this problem, but it was fixed and tested for 1.2.7, so I would say it’s a plugin
@gunju2221 nope, it don’t go away after refresh. It happens only on the person’s activity stream who is replying to a @message. When they reply it appears underneath the original @message and this is fine. When you refresh the page this is when another message appears above the threaded comments. It’s a activity comment in reply to xxxx. Not needed!
It’s not just my site, I went to buddystream plugin site just to test it. Check out my profile here http://buddystream.net/members/gearupandplay/
You will notice that when I replied to a status update I have duplicate activity on my profile.
Thats not a duplicate. When you post an update, and you reply to an update, the comment will show up underneath, and to the “In reply to” activity stream update also above it.
Oh, this is intended, seems redundant to me.
No, because it’s not going to delete the status update, just because somebody replied to it 
Ha? I don’t want to delete the status update because someone replied to it. If you follow my link above to my buddystream profile you will see the reply to the status update is posted in a threaded form underneath the original status update but also as a reply to. It takes up a lot of room just to repeat what has already been said in the threaded discussion below.

I am getting duplicate content in my activity stream on user profiles. If people talk to each other they get two updates, one being the original message and the other being the “new activity comment”. This is where it gets duplicate. How do I remove the “new activity comment” from showing up in the stream. I think this would solve the problem.
To understand what I mean a users profile would look like this.
