If i understand this correctly, it happen when you receive an update of any "Preinstalled" app, once you update the app it will have two entries in the system settings since the installation path is different ex :
Preinstalled : /usr/share/click/preinstalled/com.ubuntu.shorts/
Once the first update is applied the path will be : /opt/click.ubuntu.com/com.ubuntu.shorts/
