Ozpost - Fastway shipping not splitting boxes

Hi

I have fresh install of Zencart v1.3.9h with the following addons: oz post v2.3.1, dual pricing v1.7, nab transact v1.3, image handler v2.

I have configured the ozpost module for Australia Post and Fastway. So far this works fine until I test bulk orders.

eg. 7 products - each product is 41cm x 49cm x 9cm. This should theoretically produce two boxes to be shipped as one shipping box would fit 5 of these products.

For some reason though it it doesn't split the products? Does the ozpost module not calculate multiple shipping boxes? Or have I set something incorrectly?

Any help would be appreciated as the client would like to go live soon.

Calculations and shipping settings attached.
