Landmark Trx Node MultipleRecordQuery

I am using LPA 10.0.2 - Landmark Trx node to query the JobRequisition business class for multiple records.  Inside the trx node I have an assign node to format the results of the query then a file node to write the values from the assign node to a .csv file.  When I run the flow locally, the console shows the trx returning multiple results but the .csv file only has one row.  My assign node is a string variable which is the input for the file node. 

How do I get all the query results written to the file?
