Hi JeannieHCollaberaVendor,
This is because the ability to import a schema from a database or .dacpac file is only available when no schema objects have been defined in the project.
You can add a new project to the solution by right-clicking the solution-> Add ->New Project.
Then you can import database to the new object.
Best Regards,
Amelia
