Radio Control not appearing as selected during page loads

Hi Team,

If I add an radio control in one of the cases of xforms:switch wrapped by an xforms:group, then the radio control is not showing as selected when the page loads.

However if I add this control outside of the group and switch case, then it’s working fine.

Please provide some solution.

<xforms:switch>

                <xforms:case id="showspambar">

                                <div class="linewrapper">

                                                <span class="labelwrapper align-left">

                                                                <span class="label strong">Mailboxbeveiliging</span>

                                                </span>

                                                <span class="control decorated" id="linkid">

                                                                <xforms:trigger appearance="minimal" id="wijzigenlink">

                                                                                                <xforms:setvalue ev:event="DOMActivate" ref="instance('email_instance')//showsuccess" value="'false'"/>

                                                                                <xforms:toggle case="showspamsetttings" ev:event="DOMActivate" />

                                                                </xforms:trigger>
