Why does it seem like my ternary operator in laravel is not working

Hi so i have a ternary operator that I used to assign a variable , i have used it on my other functions and it is working but in this one it is not , i compared the both of them and there is nothing different about them . can someone tell me whats the problem here ? here is the code for it

$sesh_id = session('id');
$filter = $sesh_id == 1 ? "Reserved" : $sesh_id == 2 ? "Borrowed" : "Returned";

the sesh_id is getting the value so i really dont know what triggers the problem .
