County ISO and translations for Cork County (Ireland) in invalid

[lezwon]

The ISO and translation for Cork Country in Ireland seems invalid.
Cork ISO is CO not C.
And the english translation is not Connacht, it's Cork.
Connacht is a province in Ireland, not a county.
Reference: https://www.wikidata.org/wiki/Q162475
Github: IE.yaml
I am trying to populate my DB for Ireland states. Following is my code:

iso = 'IE'
country = ISO3166::Country.new(iso)
states = country.states.select { |_iso, data| data.name.present? }.map do |iso, s| 
   { iso: iso, name: s['translations']['en'] } 
end

Following is the response. My issue is that Connacht should not be present in this list as it is a province instead of a county. Please do correct me if I’m doing something wrong.
