I would probably be tempted to delete (or save elsewhere) the default Beechcraft Baron folder via Windows Explorer/File Manager and then run the X-Plane Installer application.
By so doing, the installer app will scan your X-Plane 11 file structure, recognise that the default aircraft folder is missing and then download/install the relevant files again.
This is the only way I can think of to 'reset' the aircraft so to speak and it will be quicker than redownloading the whole X-Plane 11 file structure again.
Be careful though, I'm not sure which version of X-Plane 11 you are running, but if you use the installer app at any time, then you will get the latest iteration of X-Plane 11 only and won't then be able to roll it back to an earlier version if you have one!
Hope this helps and if so, perhaps you would be kind enough to consider giving my response a positive upvote as per the suggestion on the Q&A webpage.
Kind regards and thanks in advance
