Marketpress: How to remove State/Province/Region from SHIPPINGINFO?

This old forumpost describes how to remove the input-field from the page templates alright.

However it remains as output on the /store/order-status/ordernumber-page & in the emails (order confirmation etc.) sent.

you can still see the line:

“State/Province/Region: CLICK TO SELECT”

It still resides in SHIPPINGINFO.

Where can I please change this, so that “State/Province/Region: CLICK TO SELECT” doesnt appear anymore also in the output?
