Unicorn won't point towards other rails project

The unicorn server seems to be continuing to look at rails_project, despite the fact that I’ve edited it to point towards my own project (wll-rails-project).

I have followed

https://www.digitalocean.com/community/tutorials/how-to-use-the-ruby-on-rails-one-click-application-on-digitalocean

I have changed the unicorn log to point to my custom app

listen "unix:/run/DigitalOceanOneClick/unicorn.sock"
worker_processes 4
user "rails"
working_directory "/home/rails/wll-rails-app"
pid "/run/DigitalOceanOneClick/unicorn.pid"
stderr_path "/var/log/unicorn/unicorn.log"
stdout_path "/var/log/unicorn/unicorn.log"

and executed 

service unicorn restart

but the unicorn log seems to keep referring to the orginal rails_project: 


the unicorn log is:
