That is a classic lesson to learn! Your experience with the service in Ireland highlights exactly why this is so confusing: geography dictates the terminology.
The reason the Irish service corrected you is likely due to the "International CV" nuance.
If you apply for a marketing job in Dublin or London, they will ask for a "CV." However, if you send them a 6-page document listing every seminar you attended in 2015, they will reject it. In Europe/UK, when they say "CV," they usually mean "A 2-page document that acts like an American Resume."
