How to change link in Customizing menu

I am trying to change the link in the Customizing Menu -> Primary menu - > Sales Training.
However, I cannot see where is let's me change or edit where this link goes to from the header bar. It shows the link or Remove. I want to edit it.
My site is sales-getters.com.
I want the Sales Training link in the menu bar to go to http://sales-getters.com/wp-admin/post.php?post=596&action=edit

Thank you.
