Why does the Device log out after changing the password?

Question

Ruby on Rails

Hello, I can not get the Device gem, I will be grateful for any help.
The administrator can change his email and password.
If he changes the password, then he throws it out on the authorization page.
If the email changes, then everything is fine.
How to disable this feature?
Devise 3.5.6
Controller:

def update_profile
    if current_admin.update(admin_params)
      redirect_to dashboard_settings_path
    else
      flash[:errors] = current_admin.errors.full_messages.to_sentence
      render :index
    end
  end
  ....
  private
  def admin_params
    params.require(:admin).permit(:email, :password)
  end

Before the redirect you need to add
sign_in(current_admin, bypass: true)
