Symfony Migrations Bundle creating the same migration over and over again

I added an auto-update timestamp to an entity like in this blog post and it works just fine.

Here is the code snippet:

#[Entity]
class Article
{
    #[Column(type: "datetime",
        columnDefinition: "TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP",
        insertable: false,
        updatable: false,
        generated: "ALWAYS")]
    public $created;
}

The first time I run php bin/console make:migration the correct migration is generated:

$this->addSql('ALTER TABLE article ADD created TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP');

This works just fine and any DB update now updates created. However, this is also where the problems begin. Whenever I make another migration now, it tries to apply the same changes again:

$this->addSql('ALTER TABLE article CHANGE created created TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP');

How can this be, and does anyone know how to fix this?

Thank you very much for your input, I really appreciate it.
