TestNG results groups on Jenkins

I have a tests suites as below

<!DOCTYPE suite SYSTEM "http://ift.tt/19x2mI9" >
<suite name="SailPoint IIQ Suite" preserver-order=true>
    <suite-files>
        <suite-file path="Test1.xml"></suite-file>
        <suite-file path="Test2.xml"></suite-file>
        <suite-file path="Test3.xml"></suite-file>
    </suite-files>
</suite>

So , I want Jenkins should show, test results tables based on Suites Names but it shows tables based on Java package names as
