String select appear as '[object]' in list view

[mingard]

Use this example field:

"vendor": {
      "type": "String",
      "label": "Payment Vendor",
      "required": false,
      "validation": {
        "regex": {
          "pattern": "[paypal|stripe]"
        }
      },
      "publish": {
        "multiple": false,
        "section": "Payment",
        "placement": "sidebar",
        "display": {
          "list": true,
          "edit": true
        },
        "options": [
          {
            "value": "paypal",
            "label": "Paypal"
          },
          {
            "value": "stripe",
            "label": "Stripe"
          }
        ]
      }
    }
  }

• Create a new document with this value selected
• Go to the collection list view
• Observe that the value rendered is always [object] rather than "stripe" or "paypal"

I presume that what it's doing is selecting the object from the list of options, but rendering the option rather than option.label
