What does that mean

What are the risks

People you don't want viewing your posts
Everything will be indexed and squirreled away forever even after you delete it.

What do I do to fix it

Go and fix your old posts
Change your settings

 Swipe your feed to the right to expose the menu and then scroll all the way to the bottom.

 Make sure friends is selected
Now make a test post and make sure friends is selected.
