Chrome changes the subdomain I enter to a different, cached one (MAMP localhost)

Question

Has anybody noticed that Chrome sometimes changes a URL you enter to a slightly different one that you've entered before? Going Incognito fixes the problem, but I want to clear the cached URL, or tell Chrome to not change to these anymore.

I set up a new WordPress site using MAMP. I like to add subdomains for new projects, so I added 127.0.0.1 newsite.localhost to /etc/hosts and added a VirtualHost to MAMP's httpd.conf, putting newsite.localhost below oldsite.localhost (where oldsite is another project). I navigate to newsite.localhost and Chrome changes it to oldsite.localhost. I can only reach newsite through an Incognito tab

All of the combinations redirect to oldsite.localhost

http://localhost
localhost
http://newsite.localhost

etc..

EDIT: Here is the relevant part of my /etc/hosts file:

127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
192.168.64.2    localhost
127.0.0.1       oldsite.localhost
127.0.0.1       newsite.localhost

And MAMP's httpd-vhosts.conf

<VirtualHost *:80>
    ServerName newsite.localhost
    DocumentRoot /Users/jared/work/MAMP-hosts/new-site
</VirtualHost>
