Regarding the export_config for exporting only the specified range in uvTiles.

When attempting to export a single texset with two UV tiles via the API, even though the export_config specifies the range as 'uvTitles': [[2, 1]], unnecessary textures within the range 'uvTitles': [[1, 1]] are also being exported. Is this a bug? Below, I have attached the complete JSON configuration used for the export.
