Prestashop 1.6.1.6 Country ISO code Kuwait payment error

[GTR]

Hi,

 

Our payment module send ISO codes for validation, only country that has a 3 letter ISO code is Kuwait (KWT).

The module only accepts 2 letter ISO codes.

So I try to change the ISO code to KW so payment can be done but I get an error message saying

 

"there already is a country with KW and cannot have 2 of the same ISO codes"

 

I have checked the list manually and with search, but no other country has the KW ISO code.

 

So why can't I change the Kuwait ISO code from 3 to 2 letters?
