I am using the Odoo free account online, and in my Point Of Sale, when I click on the top tab "Unknown Customer" I can select the customer and also I can add new customers.
But when I install the Odoo in my own server "Amazon EC2 instance from pragmatic":

I can´t see the button, I cheked the options but I can´t find the solution.
How can I add the new customer button on my POS?
You can see a screenshot of the button:
