Lost manual sorting of images since upgrading from Kirby v3.9 to v4

I seem to have lost manual sorting of images when upgrading from Kirby 3.9 to Kirby 4?

      gallery:
        headline: Available images
        type: files
        template: default
        query: page.images
        layout: cards
        size: large
        back: grey
        limit: 8
        image:
          cover: true
          ratio: 3/2
          back: white

Anyone have any ideas?

Also on the image, from the ‘3 dots menu’, ‘Change Position’ is also greyed out.

Also when you remove query?

Thanks texnixe, that did the trick, but I’m not sure why it worked on the older kirby version?

Because there was no query property for files sections before, so it was ignored.

As ever texnixe, you are a font of knowledge, thank you.
