Are you able to provide the full output of php please support:details?

[eminos]

Sorry about that. I thought I provided the Statamic version at least, which I assume would be most important in this case, but I didn't. It's Statamic 5.30.0 (latest as of writing).

Anyway I see there's a PR now fixing this issue.

Can confirm. I stumbled upon this a few days ago as well!

for example this:

tabs:
  main:
    display: Main
    sections:
      -
        fields:
          -
            handle: title
            field:
              type: text
              required: true
              width: 50
              localizable: false
              validate:
                - required
              display: Name
          -
            handle: stars
            field:
              options:
                -
                  key: 1
                  value: '1'
                -
                  key: 2
                  value: '2'
                -
                  key: 3
                  value: '3'
                -
                  key: 4
                  value: '4'
                -
                  key: 5
                  value: '5'
              default: 5
              type: button_group
              display: Sterne
              localizable: false
              width: 50
          -
            handle: quote
            field:

              localizable: true
          -
            handle: company
            field:
              type: text
              display: Firma
              localizable: false
              width: 50
              listable: true
              validate:
                - required
          -
            handle: position
            field:
              type: text

As mentioned above, it's only about the selection state that is not displayed correctly. The data saves fine and correctly.
