Getting Partial response from kie-server Restful webservice

Issue

I am passing multiple OrderEntries as a fact in my request payload to kie-server container, but while receiving response I am getting only one element of OrderEntries.

Here is my payload request.

<batch-execution>
  <insert out-identifier="order" return-object="true" entry-point="DEFAULT">
    <com.example.OrderImpl>
      <totalValue>1000</totalValue>
      <totalOrderQuantity>10</totalOrderQuantity>
      ...
    </com.sample.OrderImpl>
  </insert>
  <insert out-identifier="orderEntry" return-object="true" entry-point="DEFAULT">
    <com.sample.OrderEntryImpl>
      <ID>1001-CT</ID>
      ...
    </com.sample.OrderEntryImpl>
  </insert>
  <insert out-identifier="orderEntry" return-object="true" entry-point="DEFAULT">
    <com.sample.OrderEntryImpl>
      <ID>1002-CT</ID>
      ...
    </com.sample.OrderEntryImpl>
  </insert>
  <insert out-identifier="orderEntry" return-object="true" entry-point="DEFAULT">
    <com.sample.OrderEntryImpl>
      <ID>1003-CT</ID>
      ...
    </com.sample.OrderEntryImpl>
  </insert>
  <fire-all-rules/>
</batch-execution>

Here is a response.

<org.kie.server.api.model.ServiceResponse>
  <type>SUCCESS</type>
  <msg>Container testContainer successfully called.</msg>
  <result class="execution-results">
    <result identifier="orderEntry">
      <com.sample.OrderEntryImpl>
        <ID>1003-CT</ID>
        ...
      </com.sample.OrderEntryImpl>
    </result>
    <result identifier="order">
      <com.sample.OrderImpl>
      <totalValue>1000</totalValue>
      <totalOrderQuantity>10</totalOrderQuantity>
       ...
      </com.sample.OrderImpl>
    </result>
    <fact-handle identifier="orderEntry" external-form="0:34:1291910638:1291910638:34:DEFAULT:NON_TRAIT:com.sample.OrderEntryImpl"/>
    <fact-handle identifier="order" external-form="0:31:70403732:70403732:31:DEFAULT:NON_TRAIT:com.sample.OrderImpl"/>
     </result>
</org.kie.server.api.model.ServiceResponse>

i.e. I expect to get all of three orderEntry elements in response, but got only one element .
