If you want to see only one copy, you will need to uninstall them ALL (yes, all), the reinstall only the most current version. As explained in the other thread, the result is just cosmetic so you won't see multiple version in the Control Panel, but the Addon Manager installer is always one, there's no duplication of files by installing multiple times.
