Newbie needs help

Hello,

Woke up this morning and my stick was totally wiped!!

I have installed Kodi. When I click on it and “choose your weapon”. There are no files under the green Android for me to select. I’m sure that maybe something simp,e needs to be select / deselected, but unable to find it.

I am not using a computer, using fire stick

Thanks, would be really grateful for some help here.
