Extracting Unique Country Count from LinkedIn About Page Using Claygent

hey I'm trying to use claygent to extract the number of unique countries a company operates in based on the number of locations mentioned on their linkedin about page/the locations section on that page. the problem I'm having is that claygent is returning that a company operates in 2 countries if they operate in 2 cities even when I mention in the prompt to return unique countries they operate in rather than cities how can I change the prompt to make it return only the number of countries they operate in
