Repeater `defaultItems()` not works

The

Repeater

Repeater

displayed empty until pressing the add button. I want to display a specific numbers. As I know it's by setting it like

->defaultItems(2)

->defaultItems(2)

but not works. Am I missing something?

Forms\Components\Repeater::make('blogs')
  ->schema([
      Forms\Components\TextInput::make('title'),
  ])
  ->defaultItems(2),

Forms\Components\Repeater::make('blogs')
  ->schema([
      Forms\Components\TextInput::make('title'),
  ])
  ->defaultItems(2),
