Subservers and subdomains are created with wrong directory

When creating sub-servers and sub-domains, the Apache DocumentRoot is getting set to /home/domain/public_html/subdomain instead of /home/domain/domains/subdomain.com/public_html. This is on a system that's been running Virtualmin for ~2 years and seems reminiscent of the old subdomain directory layout...

Where do I need to go to change this to the correct setting?
