Adding a plugin in Sanity.io and resolving conflicts with existing documents.

does anyone know how i could come across these errors? i haven't really messed with anything within sanity yet except adding a plugin

Which plugin did you add? It seems like you already had your page and settings document but the plugin added its own too.
So if you want to use the plugin you will have to remove the page and settings documents you created

this helped, thank you!

You are welcome
