Why are you saving the factory? Shouldn't you save/persist the Content itself?

[Saltibarsciai]

The same result is got when using

$this->factory->save($content);

or

$manager->persist($content);
$manager->flush();

Initially I used factory because bolt5 docs recommended it https://docs.boltcms.io/5.0/extensions/creating_content
