Check box is not a textTab
(which translates to a data field in the Console UI). To specify a checkbox in the xml format try this:
<tabs>
<textTabs>
<text>
<tabLabel>ApplicationNumber</tabLabel>
<value>APPLICATIONNUMBER</value>
</text>
</textTabs>
<checkboxTabs>
<checkbox>
<selected>true</selected>
<shared>false</shared>
<tabLabel>checkBoxLabel1</tabLabel>
</checkbox>
<checkbox>
