Why does the EN-US version of MS Office appear twice in Add/Remove Programs?

  1. Please see beneath. I numbered the two instances of EN-US.

  2. How can I uninstall other language versions of MS Office, without uninstalling English? Is it fully safe for me to select the Japanese and Taiwanese versions of Office below, and uninstall them? I’m too afraid to try because I don’t want to accidentally uninstall the English version.
