Webhook API_ImportFromCSV trapped in loop and adding blank records

I am using the predecessor update web hook functions from the "ABC Project Manager Template Edition" sample database, to update the parent child relationship in my tasks table. 
The web hook is changing the data correctly, but continues to run adding blank records to the table in a loop. I have to disable the web hook to stop the add.
 
This is only on one table and the [Record ID#] (3) is the Primary Key I am updating the [Related Master Task] (9) with the content of [Derived Related Task]. 

Here is the body
<qdbapi>
<udata>mydata</udata>
<usertoken>"My Token is here"</usertoken>
<apptoken>"My Token is here"</apptoken>
<records_csv>
<![CDATA[
%RepeatOn%
[Record ID#],[Derived Related Task]
%RepeatOff%
]]>
</records_csv>
<clist>3.9</clist>
</qdbapi>
