hide Contact Author tab – how ?

8.7 beta

i’d like to hide the Contact Author tab on the listing detail page

i enabled Enable Custom Display on General Settings > Page Setup > Listing Page

but i didn’t see where to remove just the Contact Author tab

<a name="toplisting"></a>
 
<div class="pull-right hidden-xs">[D_SOCIAL]</div>
 
<h1>[TITLE]</h1>

<div class="mainlocation">[LOCATION]  [phone] </div>
 
<div style="border-top:1px solid #efefef; margin-top:10px; margin-bottom:10px; padding-top:10px;">
[RATING class='pull-right']
[BTN key="url" text="Visit Website"]  [FAVS class='btn btn-primary'] [CONTACT style=1]
</div> 

<div class="panel panel-default">

<div class="panel-body">   

[IMAGES type="images"]

<div class="clearfix"></div>

<hr /> 

[GOOGLEMAP text_after="<hr />"]

<div class="clearfix"></div>

<div class="pull-right hidden-xs">[DATE]</div>
        
<ul class="nav nav-tabs" id="Tabs">
        
        <li class="active"><a href="#t1" data-toggle="tab">{Description}</a></li>
        
        <li><a href="#t2" data-toggle="tab">{Details}</a></li>
        
        <li><a href="#t4" data-toggle="tab" >  </a></li>
        
</ul>
 
<div class="tab-content">
        
        <div class="tab-pane active" id="t1">[TOOLBOX] [CONTENT] <hr /> [RELATED]  </div>
        
        <div class="tab-pane" id="t2">[FIELDS hide="map"]</div>
        
        <div class="tab-pane fade" id="t4">[COMMENTS tab=0]</div>
       
</div>

</div></div>
