I am trying to display records grouped by Module custom field in standard Contact object using Salesforce LWC. There are records displaying so far, but only Module and Name values are visible. Been trying to display also Email and Phone values, but unfortunately only the headers are visible.I have already tried searching for same scenarios and modified codes many times but still haven't had any progress with it,

Meanwhile, here's what I achieved:

contactLWC.html

<template>

    <table class="slds-table slds-table_cell-buffer slds-table_bordered ">
     <thead>
      <tr class="slds-line-height_reset">
       <th class="" scope="col">
        <div class="slds-truncate" title="contactModule">Module</div>
       </th>
       <th class="" scope="col">
        <div class="slds-truncate" title="contactName">Name</div>
       </th>
       <th class="" scope="col">
        <div class="slds-truncate" title="contactEmail">Email</div>
       </th>
       <th class="" scope="col">
        <div class="slds-truncate" title="contactPhone">Phone</div>
       </th>
      </tr>
     </thead>
     <tbody>
      <template if:true={mapData}>
       <template for:each={mapData} for:item="keyValue">
        <tr key={keyValue.key} class="slds-hint-parent">
            <th scope="col">
                <div>{keyValue.key}</div>
            </th>
            <template for:each={keyValue.value} for:item="value">
                <div key={value.Name}>
                    {value.Name}
                </div> 
                <div key={value.Email}>
                    {value.Email}
                </div> 
                <div key={value.Phone}>
                    {value.Phone}
                </div> 
            </template>
        </tr>      
       </template>
      </template>
     </tbody>
    </table>
</template>

                if (data.hasOwnProperty(key)) { 
                    this.mapData.push({key: key, value: data[key]});
                }

     for(Contact contObj:contactList)
     {
      List<ContactWrapper> conWrapperList = new List<ContactWrapper>();

      if(mapModule.containsKey(contObj.Module__c))
      {

       conWrapperList = mapModule.get(contObj.Module__c);


       conWrapperList.add(new ContactWrapper(contObj));

       mapModule.put(contObj.Module__c, conWrapperList);


       moduleCountMap.put(contObj.Module__c, conWrapperList.size());
      }
      else
      {

       conWrapperList.add(new ContactWrapper(contObj));
       mapModule.put(contObj.Module__c, conWrapperList);


       moduleCountMap.put(contObj.Module__c, conWrapperList.size());
      }
     }

     return mapProjectType;

    }

    public Class ContactWrapper {

     public ContactWrapper(Contact contObj)
     {
      this.Name = contObj.Name;
      this.Email = contObj.Email;
      this.Phone = contObj.Phone;
      this.Module = contObj.Module__c;
     }

     @AuraEnabled
     public String Name {get;set;}
     @AuraEnabled
     public String Email {get;set;}
     @AuraEnabled
     public String Phone {get;set;}
     @AuraEnabled
     public String Module {get;set;}
    }


   }

Hoping someone could help me on this, and thanks in advance!
