The binary database used by locate (/var/lib/mlocate/mlocate.db) is updated once daily by cron, so locate will not find new files.
You can fix this by first running sudo updatedb
sudo updatedb && locate -e bench-repo
It's a good idea to use the -e flag so you only find files that still exist.
Oh and here's a bonus tip - you can get locate to give you a detailed listing by passing to ls -l
ls -l $(locate -e bench-repo)
