Whenever you publish an action, you need to go to the Sharing & Tracking tab before you are really done. The Sharing and Tracking tab (on the Manage page for your action) is where you update the auto-generated FB share, tweet, and copy-and-paste email. The Sharing & Tracking tab is only available once you publish your action.
Action Network adds confusion because it looks like you can edit those items from the right-hand sidebar on the Manage page, but any changes there do not get saved. That area is just to make you crazy.
Whenever make edits on the Sharing & Tracking tab, remember to click the blue "Save Options" button at the bottom of the page! (Ignore the boxes for the Google Ads pixel and the Facebook pixel; those are just for measuring ad campaign performance.)
