It seems that properties are sorted twice when sorting by address: successfully grouping by street, and then street number.

There is a bug with properties such as 5A Example Street - with the sorting algorithm treating these length 2 strings like they are to be sorted after the 50's for example.

It'd be great if the sorting method treated these like unit numbers to avoid putting them late in the lists.

This will help for ordering of physical marketing items and exporting.
