Activity stream module not working properly after customization

[محروم.كوم]

I tried to edit home page. Dragged the activity stream module to right side panel, so that it can show the latest activity.
But it disturbs whole activity module including the original one with 3 tabs i.e. latest activity, my subscription and directory. May be the module is same.Basically it creates duplicate tabs latest activity, my subscription and directory. Editing options doesn't work either

I tried creating new activity module and customize it, but create module only only create "ads module", no activity stream

Also can't edit/delete customs created modules __DEFINE_LIKE_SHARE__
