I get this error when I try install a module with the xml demo data below

<?xml version="1.0" encoding="utf-8"?>
<odoo>   
​<data noupdate="1">       
​ ​<record id="comp1" model="res.company">           
​ ​ ​<field name="name">Test Company</field>           
​ ​ ​<field name="currency_id" ref="base.USD"/>       
​ ​</record>       
​ ​<record id="dept1" model="hr.department">           
​ ​ ​<field name="name">Service</field>           
​ ​ ​<field name="company_id" ref="comp1"/>       
​ ​</record>       
​ ​<record id="emp1" model="hr.employee">           
​ ​ ​<field name="name">John</field>           
​ ​ ​<field name="department_id" ref="dept1"/>       
​ ​</record>   
​</data>
</odoo>

Validation Error

The operation cannot be completed: 
- Create/update: a mandatory field is not set. 
- Delete: another model requires the record being deleted. If possible, archive it instead. 
 

Model: Employee (hr.employee) 
Field: Department (department_id)

If i switch ref="comp1" to ref=" base.main_company", it works fine. Why does another company not work? I cant find any code that removes the department for some reason when creating. Im on v17
