How do I restore missing footer buttons in SW Cards?

Open Footer Content in the SW Cards module and add each call to action under Buttons. Enter the button text and link, confirm the button style, and publish the page. Buttons saved only in the older Add Button 1 or Add Button 2 fields do not move into the current Buttons list automatically, so you need to re-enter those values. If the page already uses the current Buttons list, check that every button has complete text and link settings.
