Unhiding " hide simmilar feeds"

Hi,
I have clicked " hide similar feeds" in es stream. But I want to unhide it again. Looking for the solution in this forum, I realised I have to publish activitylog in menu ( right?) .After doing that, I checked for the my activity but it only displays what I see in time line. I try change from all activity to hidden in backend. BUT, it's still same. help

Thanks
