Checked Option "Auto Reject Number"

If you have "Unknown numbers" checked, that will block numbers that are hiding their call display information (which may show up as "Unknown number" or "Private number" or something similar.

To block all calls except for ones in your contact list, you'll have to set it to "contacts only" (if there is that option - I don't remember if my S4 had it). If not your other option is to use a call blocking app from the Play store.
