Possible bug with Builder field and FileUpload

I've been chasing a bug I thought was in my project and I just want to confirm that I'm not losing my mind

Here's a simplified example:

    Builder::make('test')->blocks([
        Block::make('file')->schema([
            FileUpload::make('file'),
        ])
    ]),

    Builder::make('test')->blocks([
        Block::make('file')->schema([
            FileUpload::make('file'),
        ])
    ]),

    Builder::make('test')->blocks([
        Block::make('file')->schema([
            FileUpload::make('file'),
        ])
    ]),

    Builder::make('test')->blocks([
        Block::make('file')->schema([
            FileUpload::make('file'),
        ])
    ]),
