You need to open your Template.dwt tile and ensure that you have Editable Regions for doc title and <head> tags. Otherwise those elements are not editable from Child pages spawned from that Template.
So your Template must contain these important bits of code.
<!-- InstanceBeginEditable name="doctitle" -->
<title>Untitled Document</title>
<!-- InstanceEndEditable -->
<!-- InstanceBeginEditable name="head" -->
<!-- InstanceEndEditable -->
</head>
