Using setcontent with orderby doesn't return results

[milosa]

Contenttype:

packages:
    name: Pakketten
    singular_name: Pakket
    fields:
        name:
            label: Naam
            type: text
        price:
            label: Prijs
            type: number
            mode: integer
            step: 1
        order:
            type: number
            mode: integer
            step: 1
            label: Volgorde
    viewless: false

When I use {% setcontent packages = 'Pakketten' orderby 'order' %}, packages has no items.
When I use {% setcontent packages = 'Pakketten' %}, it has the items I expect (but obviously not ordered the way I want)

I used printquery on both.

The first one shows:

SELECT content FROM Bolt\Entity\Content content LEFT JOIN content.fields fields_order_1 LEFT JOIN fields_order_1.translations translations_order_1 WHERE content.contentType = :ct0 AND content.status = :status_1 AND fields_order_1.name = :order_1 AND translations_order_1.locale = :order_1_locale ORDER BY lower(translations_order_1.value) ASC
ct0: pakketten
status_1: published
order_1_locale: en
order_1: order

The second one shows:

SELECT content FROM Bolt\Entity\Content content WHERE content.contentType = :ct0 AND content.status = :status_1 ORDER BY content.publishedAt DESC
ct0: pakketten
status_1: published

I noticed that in the first query, order_1_locale is set to en, whereas my site is configured to be nl. nl is the only locale.
