I am getting wrong price for Fastway Satchels is anyone happen the same? or did I do some config wrong?

I tested with my store as in melb and delivery locate in brisbane 4000 and weight of 2kgs... but price always $5.50 with all sizes... (Fastway offer size A2 and A3)

also Fastway don't have satchels cost $5.50 (for melbourne price anyway)

I put "MEL" for FastWay Franchise and FastWay frequent user? YES

Please advice if i did some config wrong or is it the server calculation?

thanks
