reportExecutions REST does not apply input report parameters

I POST to execute report using reportExecution REST with values below:

<reportExecutionRequest>

    <reportUnitUri>/KBANK_Report/JBSK100</reportUnitUri>

    <async>false</async>

    <freshData>true</freshData>

    <saveDataSnapshot>false</saveDataSnapshot>

    <outputFormat>pdf</outputFormat>

    <interactive>true</interactive>

    <ignorePagination>false</ignorePagination>

    <parameters>

        <reportParameter name="Vendor">

            <value>eakandw</value>

        </reportParameter>

        <reportParameter name="Terminal">

            <value>88026820|A2032100054</value>

            <value>88026821|A2032100055</value>

        </reportParameter>

        <reportParameter name="JobType">

            <value>5</value>

        </reportParameter>

    </parameters>

</reportExecutionRequest>

then call another REST to exported the result using REST

http://172.17.24.129/jasperserver/rest_v2/reportExecutions/e873bd6a-4b37...

notice that the export result does not correct but if query report from portal it work correctly.

Did i set something not correct?
