Laravel stores to many copies of images at first time upload in storage folder

when I upload one image in Laravel it stores correctly in the database but it stores 4 times one image in the storage folder here is my function which store data from form

  public function store(Request $request)
{
    //
    $request->validate([
        'name'=>'required',
        'intro'=>'required',
        'description'=>'required',
        'profile'=>'image|nullable|max:1999'

    ]);

    $fileNameToStore='';
    if($request->hasFile('profile')){
        $fileNameWithExt =$request->file('profile')->getClientOriginalName();

        $fileName = pathinfo($fileNameWithExt, PATHINFO_FILENAME );

        $extension = $request->file('profile')->getClientOriginalExtension();

        $fileNameToStore= $fileName.'_'.time().'.'.$extension;

        $path = $request->file('profile')->storeAs('public',$fileNameToStore);

    }
    $data=$request->except('token');
    $data['profile']=$fileNameToStore;
    about::create($data);
    return redirect()->route('admin.aboute.create')->with('msg', 'Your profile
    has been added successfully');
}

I added my profile details only one time, it stores all data in database very well but, it stores my profile image in storage folder 4 times

anyone guide me why it is doing this?
