Icon in dock doesn't show correct version

“Scrivener 2” pops up when I hover over the Scrivener icon in the dock, and I have S3 (purchased from L&L). This occurred before the Mojave update.

The Dock uses the name of the application in Finder, and so you can change it by renaming the Scrivener listing in your Applications folder.

How did it happen? If you have more than one version of Scrivener installed, Finder will rename them ‘Scrivener 2,’ ‘Scrivener 3,’ and so on, rather than allowing duplicates.

Use the Scrivener -> About Scrivener command to verify what version is actually running.

Not a bug, this is simply how Finder works.
