I have created a Custom Lead Convert Page. I need to show a list of duplicate contacts on Lead Conversion. I have been trying to do so using Apex:Repeat and Apex:PageBlockTable but nothing is getting displayed. My SOQL does return results. Kindly suggest. My Controller and Visualforce Page are given below:-

VisualForce Page:

<apex:page standardController="Lead" extensions="LeadConvertController">
    <apex:includescript value="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" />

    <apex:form id="leadForm">
        <apex:pageBlock mode="edit" >

                <apex:commandbutton value="Cancel" action="{!Cancel}"/>
        </apex:pageblockbuttons>
        
        <apex:pageblocksection id="LeadConvertPBS" title="Convert Lead">
