Default sort order is different in three different pages with separate pdb_lists

I am using this plugin to show separate lists containing name, address, city, state, zip, phone number, email, and url for dealers in three separate countries with search and sort included at the top of each list. On my U.S.A. page my list automatically appears sorted in the same order as the .csv file I uploaded when the page is accessed. In my Canada list, and Australia list the order defaults to a fairly random order and is not the same as the .csv file order that I uploaded.

The code that I am using on each separate page is:

[pdb_list search=true sort=true filter='Country=U.S.A.']
[pdb_list search=true sort=true filter='Country=CANADA']
[pdb_list search=true sort=true filter='Country=AUSTRALIA']

I am not understanding why my code shows up sorted the way I want on the USA page but not the other two.

I would use order_by but it appears that it only orders by one column. I want to be able to default my page to sort first by State, then by Town, then by Business name like I have it sorted in the .csv files.

The links to these pages on my test site are:

Thanks in advance for any help…
