Article mode Buddypress Social theme

The 'More Articles' doesn't seem to work in the Buddypress Social theme. (see attachment)

Or has this something to do with the Featured post option in the Theme Options menu?
In that case? How to fill these up? What are post ID's? And where can I find this?

I'm pretty new to all this so I'm sorry if I'm asking stupid questions all the time. :slight_smile:
