That's the issue then.

You'll want to remove the older version, but first make sure that you have Opened and Saved all your Scrivener Projects in the new version; open the new version then via the File menu open the projects (there is a file management change between Scrivener 2 and Scrivener 3, so you will want to make sure you can open all your projects and save them). Be careful if you have multiple versions of a given project.

Then you will want to remove the older version in the Applications directory, which should take care of the app icon in the Dock; if it doesn't you have the steps to remove the icon.
