If I use a Domain such as Manufacturing I should not expect to see Roles such as Physician available in Contact type .
Pls see Video 
To Replicate
Using beta.erpnext.com and my v9 running Master
Create new Contact and select from the Linked Doctypes as in the screen grabs.
I cannot access domain settings in Setup on beta.erpnext.com so cannot confirm that the domain is only using a single or very few selections. But I also see this same problem on my v9 running Master anyway, where I see doctypes available in Contact which are in health although I only have Domain set for manufacturing
