Help with facebook post access

Hi,

I hope my facebook posts generated by SNAP is available to public. However, it is always posted as ‘to my friends’.

I already set public access to my posts in Facebook privacy setting, but the post sent by SNAP still show access too my friends.

Can you teach me how to make SNAP-generated posts accessible to public by default? Thank you very much.

BTW, my site is http://www.quantlego.com.
