I want delete an icon on video page of Kodi. help!

Hi, I use Kodi 17 and when I open Kodi and I go into Video page I see
——— “Categories” and under that writing there is
——— “Media Sources” with 2 icons “G” and “sda1”. Some time ago I unintentionally created “G” icon but now I want to delete this icon “G”. How can I delete it please?
Thanks
