How To Turn Off Shipping/billing Address?

Hi there

I have referred to the manual that says in settings - shipping - I can click only ship to billing address however I cannot see that button anywhere. Is this still relevant in the latest update?

I have galleries where we only deliver to the club for free distribution, however even if I turn off ask for address in the account settings under place an order, when a customer is on the checkout page there is a heading that says Shipping Address with a choice of ship to billing address or ship to different address. This is very confusing for our customers when in fact no shipping details are required at all. 

Under my shipping setting applied to the gallery I have ticked This option is for a pick up or no shipping address needed (and there are no prices entered). Yet, the shipping address/billing address is still displaying and causing a lot of confusion.

Is there some way to turn off this default please? I am also concerned that it breaches privacy around collection of data when an address is not required.

Hopefully there is a simple solution I have not found.

Thank you.

You create a shipping group that only contains a pick up option and assign that shipping group to the gallery (shipping group option when editing a gallery). 

Shipping. 

If you don't offer any shipping options you can remove the shipping options for your default shipping group.
