Removing a Score from Musescore program main page/window?

I have a number of scores that I have removed from my online MuseScore account but I can not remove them from the main window/page of the MuseScore application. I have include a screenshot that shows the scores when I open the MuseScore application. I have removed "God and God Alone" from my MuseScore Cloud account, but it still shows up and I can not remove it. This is not the only score I have removed and stills shows up. How do I remove these score names?

Also, why is the removal/deletion of scores covered in the Handbook?
