Unable to maintain Session in Laravel - php

Question

I'm using Laravel 5.3 and facing problems regarding the session which is not being preserved when I hit the URL with query string(UTM Querystring). It works fine without querystring and maintains the session.
mywebsite.com/booking (Works fine)
mywebsite.com/booking?utm_source=affiliate&utm_medium=mailer&utm_campaign=Ad2click (Destroys session as well cookies)
Wondering, what could be the reason?
public function bookProduct(Request $request){
$zone = $request->zone;
$records = Zone::where('zone_name',$zone)->get();
foreach($records as $record){
$zone_id = $record->id;
