Sitemap of Subdomain Help Please

On the bottom of my google sitemap it has my subdomain: idx.propertiesinpbc.com

It says 0% priority… and “Always” Changing.. but when I put the mouse over the link “idx.propertiesinpbc.com” on the sitemap, the status bar says it’s going to point to: “https://www.propertiesinpbc.com/idx.propertiesinpb.com” which is inaccurate. If anything it should point to “https://www.propertiesinpbc.com/idx” or “https://idx.propertiesinpbc.com”

Thanks in advance!
