Workflow Elements by Aiden Kaskela Get Results SUM returning a 0 or Null value

I have a Kaskela's Get Results query that runs on Dynamics 365 Online to calculate the sum of profit (custom field) on all products in a quote.  

I then run (in a workflow) an update passing the results of the fetch from Kaskelas Get Results into a currency field on the quote entity.  If I return the value as single money, the field stays null.  If I return the value as single decimal it comes back as zero.  

If I run the exact query through the fetch tester in XRM Tools I get the result (that I need 600) as follows:

<resultset morerecords="0">

<result>

<new_profit_sum formattedvalue="£600.00">600</new_profit_sum>

</result>

</resultset>

Fetch XML Used:

<fetch version="1.0" output-format="xml-platform" mapping="logical" aggregate="true"><entity name="quotedetail"><attribute name="new_profit" alias="new_profit_sum" aggregate="sum" /><filter type="and"><condition attribute="new_activeproducttype" operator="eq" value="100000000" /></filter><link-entity name="quote" from="quoteid" to="quoteid" alias="aa"><filter type="and"><condition attribute="quotenumber" operator="like" value="QUO-01188-L5S0Z2" /></filter></link-entity></entity></fetch>

The quote number in the workflow is passed as a field quoteid into the workflow.  For the above purposes testing in the xrm fetch tester tool I put in an actual quote number.  I also tried that in the actual Kaskela's fetch and the same thing happens so its definitely not that.

This query used to work ok but stopped working for some reason.  I updated to the latest Kaskela's 1.2.0

I have other queries that used to work and now don't.

Any Ideas what could be going wrong?
