Result of query not displaying result

I ran this query

 SELECT 
        d.dept_name, e.gender, AVG(salary)
  FROM salaries s
  JOIN 
        employees e 
        ON e.emp_no = s.emp_no
  JOIN 
        dept_emp de 
        ON de.dept_no = d.dept_no
   JOIN 
        employees e
        ON e.emp_no = de.emp_no
   GROUP BY de.dept_no, e.gender
   ORDER BY de.dept_no;

this is the result i get

why is the result wrong?
