Lite Checkout Field Arrangement Limitations For Delivery Calculation (Uk)

So the new Lite checkout looks nice but in the UK postcode is the priority to work out delivery rates rather than the County.

So wanting to swap these over under the top 'Deliver To' Block there is the option to add the Postcode, but on removing the county to keep it nice and titdy (3 in a row) you are unable to re add the county to the 'Address' block - you get less fields (only address 1&2)?

What's happening here?
