Magento 2.4.5 uninstall language pack not working

I made my own language module and now i want to uninstall it. Even when i remove the folder and do a complete new deploy, the translations are stil there.

I get the error:

bin/magento i18n:uninstall jilco/language-nl_nl

Package language-nl_nl is not a Magento language and will be skipped.
Nothing is removed.

The name in composer.json is the same:

{
"name": "jilco/language-nl_nl",
"description": "NL taalpakket",
"version": "100.0.2",
"require": {
    "magento/framework": "100.0.*"
},
"type": "magento2-language",
"autoload": {
    "files": [
        "registration.php"
    ]
}

}

What is wrong in the command to uninstall?
