There are two solutions for this case: Firstly, you could use your internal wording for the key property and the generic wording for the label property. This results in your users seeing the label and your application working with the internal wording defined in key. The second solution would be adding all generic words, which would match your internal term, to the alternativeMatches array. The alternativeMatches array contains strings or synonyms of the column from your side, which will also be checked against the imported columns.
