Issue with Multifield Container Reordering in AEM Universal Editor

[AdamTa4]

I’m running into an issue with the multifield container in AEM Universal Editor. When I try to reorder items, instead of simply moving them, a duplicate entry is created.

To reproduce:

• I have three tabs defined (tab1, tab2, tab3).

• When I drag tab3 to the second position, the result is: tab1, tab3, tab2, tab3.

So the tab I moved is duplicated: the original one moves to the target position, and a second one is created at the end.

This is my container model configuration:

  const model: ComponentModel = {
    id: componentId,
    fields: [
      {
        component: "select",
        name: "tabVariant",
        label: "Tab variant",
        valueType: "string",
        options: [
           ...
        ],
      },
      {
        component: "container",
        name: "tabSettings",
        label: "Tab Settings",
        valueType: "string",
        collapsible: false,
        multi: true,
        fields: [
          {
            component: "text",
            name: "tabLabel",
            label: "Tab Label",
            valueType: "string",
          },
          {
            component: "boolean",
            name: "tabDisabled",
            label: "Tab Disabled",
            valueType: "boolean",
          },
        ],
      },
    ],
  };

I also attached a screenshot of the nodes in CRXDE for reference.

Is this a bug in Universal Editor, or am I missing something in my configuration?

I noticed this only happens when moving the last element in the multifield.

• If I move tab1 or tab2, reordering works fine.

• If I move the last item (tab3 in my case), it gets duplicated: the original moves to the new position, and another copy is appended at the end.

So the duplication issue seems specific to the last element in the multifield container.
