Argentine Peso not showing in currency list

"Enable Currency Selection" is enabled and the Argentine Peso is included in the list of "Active currencies" but it will not show in the currency list on the front end. I've tried many other currencies and they all show fine. Any idea why this would be? Please see images for example.

I will do that ... just have to get permission from the site owner first and he's away on holiday so it may take a while.

In the meantime, I was fiddling with the site and noticed that even if I select all currencies under "Active currencies" only a very small list will actually show and the same list shows if I leave "Active currencies" blank. (see attachment)

Does this help at all?

So, after looking into it a little more it turns out the 'jd_currencies' database table only had those currencies in it. I guess it must not have imported correctly or something.

I looked at the original installation sql file (install.jdonation.sql) and only those currencies are listed. Was that on purpose or is that a bug? Here's what is in the file:

INSERT INTO `#__jd_currencies` (`id`, `currency_code`, `currency_name`) VALUES
(1, 'CAD', 'Canadian Dollars'),
(2, 'EUR', 'Euros'),
(3, 'GBP', 'Pounds Sterling'),
(4, 'USD', 'U.S. Dollars'),
(5, 'JPY', 'Japanese Yen'),
(6, 'AUD', 'Australian Dollars'),
(7, 'NZD', 'New Zealand Dollars'),
(8, 'CHF', 'Swiss Francs'),
(9, 'HKD', 'Hong Kong Dollars'),
(10, 'SGD', 'Singapore Dollars'),
(11, 'SEK', 'Swedish Kronor'),
(12, 'DKK', 'Danish Kroner'),
(13, 'PLN', 'Polish Zloty'),
(14, 'NOK', 'Norwegian Kroner'),
(15, 'HUF', 'Hungarian Forint'),
(16, 'CZK', 'Czech Koruna'),
(17, 'ILS', 'Israeli Shekel'),
(18, 'BRL', 'Brazilian Real'),
(19, 'MYR', 'Malaysian Ringgit'),
(20, 'MXN', 'Mexican Peso'),
(21, 'PHP', 'Philippine Peso'),
(22, 'TWD', 'Taiwan New Dollar'),
(23, 'THB', 'Thai Baht');

We are running an older version as the owner hasn't been willing to take the site down to upgrade as he doesn't want to lose business though I am trying to get him to. Maybe this has been fixed in newer versions?
