Add new field doesnt save / add text input to order.. or anywhere!

Hi guys,

I have just installed the free version of the woocommerce checkout manager, and disabled all fields accept Name and Email, and created a new field section.

I created a simple field with label “Where did you hear about us?” and text input type, thats it.

The problem is that anything input into this textBox is not saved or recorded anywhere.

Am I doing something wrong? or am I missing something somehwere?

Thanks
