Zenmap Recent Targets

Hello. I am a complete noob to pentesting. My question is with zenamp, how can I delete the saved list of targets that drops down when clicking on targets box of zenmap. I have searched the internet for a long time and could find nothing. When i look in the zenmap target_list.txt there is nothin the file is empty. Where are these ip addresses stored for zenmap. I am using the latest release of Kali.
