I faced the same issue. Try this sort of thing by creating formBuilder group for each row:

let employeeFormGroups = team.employees.map(employee => this.formBuilder.group(employee));
let employeeFormArray = this.formBuilder.array(employeeFormGroups);
this.teamForm.setControl('employees', employeeFormArray);
