    In the template client, everything outside <ui:composition> is ignored. You need to change your template approach to provide an <ui:insert> for the title in the master template, so that it can be defined by an <ui:define> in the template client.

    Master template:

    <!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html">

    <h:head>
        <title><ui:insert name="title">Login</ui:insert></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    </h:head>

    <h:body>
        <div id="top">
            <ui:insert name="top">
                <ui:include id="header" src="header.xhtml"/>
            </ui:insert>
        </div>
        <div>
            <div id="content">
                <ui:insert name="content" />
            </div>
        </div>
        <div id="bottom">
            <ui:insert name="bottom">
                <ui:include id="footer" src="footer.xhtml" />
            </ui:insert>
        </div>
    </h:body>
</html>

    Template client:

    <ui:composition template="/WEB-INF/templates/layout.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.prime.com.tr/ui"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html">

    <ui:define name="title">City Setup</ui:define>

    <ui:define name="content">
        <h:form id="cityReviewform">
            ...
        </h:form>
    </ui:define>
</ui:composition>
