Force Menu in Checkout Error

I´ve created a menu item for checkout wich is called pago-del-pedido
Select in hika options force a menu in checkout and select pago del pedido.
if i just type www.myaddress.com/pago-del-pedido , it leads to the checkout as expected
but the problem is that the buttons in the cart module leads to www.myadress.com/pago-del-pedido/pedido
and it results in a 404 error.

Please fill the information that is requested when you create a new thread.
Otherwise, we need to ask you anyway and both of us loose our time.
Which version of HikaShop are your using ?
Can you give a screenshot of the error ?
Did you change the "checkout sef name" option of the configuration from "checkout" to something else ? If you revert it, does it work ?

ok sorry, the problem was in the sef, changing the name does not work if i revert it to checkout fix the problem
