It is not the translation’s problem.
This module (and agenda) depends on its internationalization to Intl internal Javascript object. (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl). That is supposed to be a standard method for I18N/L10N in JavaScript world.
But unfortunately, Chromium(Electron of MagicMirror is using it) is known to have a bug in handling Icelandic locale ‘is’ or ‘is-IS’, and not been fixed yet.

Sorry. At this moment, I cannot help about it.
