Hank here from Shopify.
Would it be possible to share your store URL? That way I can take a look at your website to see what the issue might be.
Was there a time when you last remember your profiles being shown? Was anything changed since then, like a new app or changes to the theme?
Another thing I would advise doing if you do have your social media links in the footer but they are not appearing is to ensure they are in the correct format. If you go to Online Store > Themes > Customize > Theme settings > Social Media, you will see something similar to the image below. Be sure to enter in the correct format, which is shown below the text box.
But if after doing all of the above, it is still not appearing for you, simply share your store URL, and I'll take a look at this on my end.
All the best,
