Virtual servers not working

SYSTEM INFORMATION
OS type and version Ubuntu 20.02
Virtualmin version 7.1-1 Pro

I am having some issues with my newly installed virtualmin instance.

The main domain for virtualmin is ‘workaholic-studios.net’. I have set up a couple of virtual servers (as top level servers). They do not have domains yet, so I am using ‘subname.workaholic-studios.net’. Even though they all are listed as separate servers inside of virtualmin, whenever I visit any of them via their subdomain, they all go to the main ‘workaholic-studios.net’ domain and show the content on that site. I cannot figure out why.

I have the DNS records setup correctly, as prior to using Virtualmin (I used a bare-bones apache and mysql installation), everything was working correctly.
