Laravel: One to Many Poly relation not updating automatically - laravel

Question

3 types of posts: Personal, Business & Nature.
Below is the Post Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\Relation;
Relation::morphMap([
'Personal' => 'App\Personal',
'Business' => 'App\Business',
'Nature' => 'App\Nature',
]);
class Post extends Model
{
public function postable()
{
return $this->morphTo();
}
}
Below is the Personal Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Personal extends Model
{
public function posts()
{
return $this->morphMany(Post::class,'postable');
}
}
Likewise Busines & Nature models.
When I manually enter the data in phpMyAdmin, the tinker shows the result as required, but when I create a post from front-end (via form), the posts table remains unchanged.
I tried googling, but nothing works! :(
Below is the PersonalController
public function create()
{
if(Auth::guest()){
return redirect()->route('login');
}
$sectors = Sector::all();
$cities = City::all();
$ranges = Range::all();
return view('front.personal-register',compact('sectors','cities','ranges'));
}
public function store(Request $request)
{
$this->validate($request,[
"sectors" => "required",
"cities" => "required",
"ranges" => "required",
"g-recaptcha-response" => "required|captcha"
]);
$franchisee = new Personal;
$franchisee->user_id = Auth::user()->id;
$franchisee->save();
$franchisee->sectors()->sync($request->sectors);
$franchisee->cities()->sync($request->cities);
$franchisee->ranges()->sync($request->ranges);
return redirect(route('personal.index'))->with('message','Thank You! Your post has been added');
}
