BuddyPress Activity Plus not showing up on activity stream

1. I have 2 BP sites both running this plugin, and they both have the same dramas. The add media buttons do not show up on the activity stream, but so show up on the profile page activity stream.

2. when I upload images and add them to the activity the thumbnails are placed in the stream vertically (one below the other) rather than horizontally.

3. On the Activity stream when an image is clicked the lightbox does not work, it opens the images up in the parent window. but the lightbox works on the profile activity stream.

I am guessing there is some conflicting script on the home page, and the issues were noticed when I upgraded to 3.1.2
