Due to Magento limitations the attributes on an admin category pages are untranslatable.
It is a long time issue lasting from Magento 1.x.
You can fix it with a custom plugin:
di.xml:
<type name='\Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend'>
<plugin
name='Df\Eav\Model\Entity\Attribute\Frontend\AbstractFrontendPlugin'
type='Df\Eav\Model\Entity\Attribute\Frontend\AbstractFrontendPlugin'
sortOrder='100'
/>
</type>
Plugin code:
<?php
namespace Df\Eav\Model\Entity\Attribute\Frontend;
use Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend;
class AbstractFrontendPlugin {
/**
* @param AbstractFrontend $subject
* @param string $result
* @return string
*/
public function afterGetLabel(AbstractFrontend $subject, $result) {
return __($result);
}
}
