Looks like once clicking on "load more" in a group the system is fetching all sorts of data but not only the one's from that particular group.
to replicate:
you're in group A and the stream is showing only items from that group (fine).
then clicking on "load previous...." new data is loaded, unfortunately not only data from that group but also from other groups / personal profile and so on... that obviously shouldn't be the case
details for test site attached
