Right Nav Bar error, Not authenticate in Laravel - php

Question

In my web-app i made a profile section . But the problem is when it goes to dashboard in right-navbar it has my profile and logout. when i click on my profile-> in my profile page the right-navbar became register and sign in instead of name and logout. I think some authentication issue is there. please suggest how to fix it. check screenshots also for better understanding.
app.blade.php
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<!-- Left Side Of Navbar -->
<ul class="navbar-nav mr-auto">
</ul>
<!-- Right Side Of Navbar -->
<ul class="navbar-nav ml-auto">
<!-- Authentication Links -->
