Hello there,
Thanks for reaching out! It looks like you are signed into a different account through the plugin currently, presumably an account where you were previously trying a setup that had two buttons.
In order to see the changes that you are making in your dashboard that has separate buttons for your two sites, first you'll want to disconnect your plugin. You can do so by going in your WordPress admin to the Installed Plugins section and clicking on Settings for the Buttonizer app:
Then scroll down on the next page and click on the Disconnect button:
Once you have disconnected this way, you can connect the app again and choose the correct site while connecting. Once you have done this for both sites, they will be pointed at the correct Buttonizer information, and you should see the singular buttons that you have been working on.
Let me know how it goes. Cheers!
