Connected but Not Bringing in My Wordpress Posts

My app keeps defaulting back to something weird even when I select a blank app it shows a shopping app. It also won’t bring in my wordpress posts even after I installed the plugin and have the green “connected” for the connection. I have no idea what is going on, but it isn’t saving anything I do. and it won’t give me a blank app to start with and keeps updating with this template I didn’t pick.

Is there a way to start over again?
