getFlashdata is not clearing the message

I am using codeigniter4 and uses the following code

In the controller -

$this->session->setFlashdata('success','Your  Data is saved'); 
return view('dashboard');

In the View
               <?php if (session()->get('success')): ?>
                  <div class="alert alert-success" role="alert">
                    <?= session()->getFlashdata('success'); ?>
                  </div>
                    <?php endif; ?>
                  </div>   


As per  code igniter 4 , this flashdata should clear . But flashdata shows in the second page also . Then it clears on the third page .

If you echo the view instead of returning the view doe's it still do it?

it is the same issue with the echo view

Echo view also does the same issue
