ng-repeat shows another ng-repeat data - angularjs

Question

Hi i am trying to show up 2 menu's
Deparments -> subdepartments
List item
onclick of "event" button
should show up. onclick of "dates", button
should show up.
Here the issue is both the 1) and 2) display in single menu though both the htmls are different. Where am i going wrong.Below is the code.
HTML:
<div class="tab" >
<div class="sidebar-top">
<ul class="nav nav-pills nav-justified">
<li class="active">Event</li>
<li>Date</li>
</ul>
</div>
<div class="tab-content clearfix">
<div class="tab-pane active" id="1a">
<ul class="nav nav-sidebar">
<li class=" nav-active active"><i class="icon-home"></i><span>Dashboard</span></li>
<li class="nav-parent" ng-repeat="(key, value) in getdatewasedetails | groupBy: 'depatName'">
<i class="fa fa-link"></i><span></span>{{ key }} <span class="fa arrow"></span>
<ul class="children collapse" ng-repeat="subdept in value">
<li > {{ subdept.serviceName }} </li>
</ul>
</li>
</ul>
</div>
<div class="tab-pane" id="2a">
<ul class="nav nav-sidebar">
<li class=" nav-active active"><i class="icon-home"></i><span>Dashboard</span></li>
<li class="nav-parent" ng-repeat="(key, value) in getdatewasedetails| groupBy: 'month'">
<i class="fa fa-link"></i><span></span>{{ key | date:'MMMM' : 'UTC' }} <span class="fa arrow"></span>
<ul class="children collapse" ng-repeat="currDates in value">
<li > {{currDates.testDate | date:'longDate' : 'UTC'}} </li>
</ul>
</li>
</ul>
</div>
</div>
</div>
