Discard row expr with string condition check not working.

Hi Adobe, 

I am using adobe sdk service to generate a pdf from (word+json). As my requirement is to create a table on a specific check. Like I have a method inside my json and for method = "Payout by Cheque" it should print all row data of  where method = "Payout by Cheque" and rest row should be discarded.

https://developer.adobe.com/document-services/docs/overview/document-generation-api/tablewithmarkers/ as in the documentation it is shown that it is working. 

I am attaching my json file, my word template and my pdf output.
Thanks.
