Issue with using nested json in smart markers

Hi team,
I have a use case to support nested objects to export using smart markers, i’m facing issues when using that attaching the sample data, template and output files, and when i try to use indexing with array then output comes blank, please let me know what is the issue and also can smart markers handle more than 1 level of nesting?
