Adobe Pdf Generation api - if else conditional statement in table not working

Hi Adobe Support Team,

I am using this json to get binded to template and create pdf . I had to use field2 in two columns of table conditionally:

{
    "form_fills": [
        {
            "field1": "x",
            "field2": "No Contact",
            "field3": "comments"
        },
        {
            "field1": "y",
            "field2": "Contact",
            "field3": "no comments"
        }
    ]
}

I am using below template table with placeholders. 

Can you please suggest what could be the issue. Same expression outside of table would work for a single value . for table type of data, it is not working.
