Problem with the stock entry

Hi ,

Every time I open the stock entry module , it automatically picks this qty in the sort view button and I am getting this error ,

Traceback (most recent call last):
  File "/home/ommi/frappe-bench/apps/frappe/frappe/app.py", line 55, in application
    response = frappe.handler.handle()
  File "/home/ommi/frappe-bench/apps/frappe/frappe/handler.py", line 19, in handle
    execute_cmd(cmd)
  File "/home/ommi/frappe-bench/apps/frappe/frappe/handler.py", line 36, in execute_cmd
    ret = frappe.call(method, **frappe.form_dict)

    return fn(*args, **newargs)

    result = self.build_and_run()
  File "/home/ommi/frappe-bench/apps/frappe/frappe/model/db_query.py", line 103, in build_and_run
    return frappe.db.sql(query, as_dict=not self.as_list, debug=self.debug, update=self.update)
  File "/home/ommi/frappe-bench/apps/frappe/frappe/database.py", line 148, in sql
    self._cursor.execute(query)
  File "/home/ommi/frappe-bench/env/local/lib/python2.7/site-packages/MySQLdb/cursors.py", line 205, in execute
    self.errorhandler(self, exc, value)
  File "/home/ommi/frappe-bench/env/local/lib/python2.7/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler
    raise errorclass, errorvalue
OperationalError: (1054, "Unknown column 'qty' in 'order clause'")

And when I change this qty to title , I am able to open the stock entry ,

How do I get out of this problem ?

Thanks
