getCatalog return only a part of the locales

[SimoneMSR]

My installation work perfectly, but when I try to get all the translations with getCatalog I get only the current locale translations.

const i18n = new I18n({
  locales: ["en-US", "it-IT"],
  directory: path.join(__dirname, "i18n"),
  header: "ignore-this",
  defaultLocale: "en-US"
})
....
this.expressApp.use(i18n.init)
this.expressApp.use((req, res, next) => {
  res.setLocale(i18n.getLocale())
  next()
})
....
i18n.getCatalog() // return only the content of .json file for current locale
