After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
This is because in the template apps we pull the info on which basemaps to display from a request we make to ArcGIS Online to get the info for that org. If you are not signed in to an org you'll get the default values back.
In the download use case you can modify the template app to point to the basemap gallery group id that contains the basemaps with polish names.
