Freight-In problem with BAS report (Australia)

When using the Freight-In function to spread freight costs across items purchased, the pre-GST value of freight is not being picked up in the Business Activity Statement report, but the GST value is

eg If an item is purchased for $10 + $1 GST, Freight-In of $5.00 + $0.50 GST the results are:

G11 on BAS shows $10 (the inc GST value of only the goods)
1B on BAS shows $1.50 (the GST component of both the goods and the freight cost)
