You've dragged-and-dropped a social block into your campaign and see that the block was added but social link images to do not display:
In order for social image to display in a social bloc, you will first need to add the social links in your account settings. To do this, you will simply:
1. Save the campaign you are currently working on so as not to lose your work :)
2. Go to store Settings>Social links
3. Add social links to the platforms you'd like added in a social block and click save
4. Return to your campaign and drag in a fresh social links block. Walla! Social icons will now display.
As always, please feel free to contact us at firstname.lastname@example.org if you are still having any trouble and we will be happy to help.
