Shipping Method Title appearing incorrectly

Hi there, and thanks for your help in advance.

My site: http://69th-dept.com/shop

The guide regarding shipping rates states:

Syntax: Max weight|Cost|Country Group number|Method Title

So I inputted the following:

1|25|1| EMS UK & Eire
1|20|2| EMS North America
1|23|3| EMS Continental Europe
1|26|4| EMS Scandinavia
1|27|5| EMS Australasia
1|22|6| EMS Russia & Central Asia
1|26|7| EMS South America

My cart’s shipping calculator worked fine for calculating the costs, but every single option would return the first ‘Method Title’.

Inputting a US address got UK & Eire, inputting a Brazilian address got the same etc.

So I deleted the last column, as it stands the shopping rates input box contains the following:

1|25|1|
1|20|2|
1|23|3|
1|26|4|
1|27|5|
1|22|6|
1|26|7|

However, my cart shipping calculator still returns ‘EMS UK & Eire’…

I deleted the plugin, deleted all it’s files, reinstalled the plugin and inputted the above (without the last column)… and the problem persisted.

I don’t have any caching on the site, but thought maybe it’s my browser cache, cleared that, the same… checked via a different browser and same error. I checked my hosting isn’t caching too.

Any idea’s?
