PageBlock not Refreshed When 'Field' is Included in the Custom List of History Tracking

I am working on History Tracking for one of my custom object and want it to be displayed in a customized fashion. I made two page blocks; 1st page block displays the items in grid with a link in first column as History (rerendered the 2nd page block on its click). In 2nd page block I created a Apex:pageBlockTable to display CreatedBy, CreatedDate, Field, OldValue, NewValue. This 2nd page block displays the History respective to the item clicked in the 1st page block.

 

Problem:

Everything works as supposed only when I exclude the Field column. If I put the field column in my 2nd page block, pageblock is not refreshed and nothing is displayed.

<apex:form id="pixelReqForm">        
       <apex:pageBlock title="Pixel Request Form (PRF)" id="PixReqForm"><br></br> 
         <apex:pageBlockTable value="{!PixelReq}" var="aPixelReq"  id="pixelReqTable">         

            <apex:column headerValue="History" id="hisTrack">
                <apex:commandLink value="History" reRender="pixelReqHisTable">
                    <apex:param name="pixelReqID" value="{!aPixelReq.id}"/>
                </apex:commandLink>
            </apex:column>

            <apex:column headerValue="Delete" id="isDeleteColumn">
                <apex:inputCheckbox value="{!aPixelReq.isDeleted__c}" id="isDelete"/>
            </apex:column>

            <apex:column headerValue="Agency">
                <apex:inputField value="{!aPixelReq.Agency__c}"/>
            </apex:column>           
                      
        </apex:pageBlockTable>        
      </apex:pageBlock>     
      
       <apex:pageBlock title="Pixel Request Form (PRF)" id="pixelReqHistBlock"><br></br> 

         <apex:pageBlockTable value="{!PixReqHistory}" var="aHistory"  id="pixelReqHisTable">          

            <apex:column headerValue="Created By" id="createdBy">
                <apex:outputField value="{!aHistory.CreatedById}"/> 
            </apex:column>           
            
             <apex:column headerValue="Changed Field" id="changedField">
                <apex:outputField value="{!aHistory.FIELD}"/> 
            </apex:column>           
            
        </apex:pageBlockTable>                
      </apex:pageBlock>     
      
    <apex:pageBlock title="PRF History Tracking" id="histIFrame">   

 </apex:form>
 </apex:page>

===============================
Controller:

...
List <PixelReqForm__History>  pixReqHist;
    
    public List<PixelReqForm__History> getPixReqHistory() 
    {
        pixReqHist = [Select Id, IsDeleted, ParentId, CreatedById, CreatedDate, Field, OldValue, NewValue FROM PixelReqForm__History 
        where PARENTID = :ApexPages.currentPage().getParameters().get('pixelReqID') order by createdDate desc];
    
        return pixReqHist;
    }
...

Put the pageblock in an output panel and try with apex:outputText instead of outputFiled
