Nativescript ListView shows only one item

Question

I am following a multiple spectrum course, and I have run into an odd problem. In my list view, only the first item is displayed and nothing else. This is odd, and I used listviews without problems before I’m not sure where the error is coming from.

Layout:

    <Page xmlns="http://schemas.nativescript.org/tns.xsd"
 loaded="pageLoaded">
  <GridLayout rows="auto, *">
    <!-- Header -->
    <StackLayout cssClass="page-header">
      <Label text="Header" cssClass="page-title bold" horizontalAlignment="center" margin="15"/>
    </StackLayout>

    <!-- Sessions Views -->
    <GridLayout rows="auto, *" row="1"> 

      <ListView items="{{ sessions }}">
        <ListView.itemTemplate>
          <Label text="{{ title }}"/>
        </ListView.itemTemplate>
      </ListView>

    </GridLayout>
  </GridLayout>
</Page>

Typescript:

import { EventData, Observable } from "data/observable";
import { Page } from "ui/page";

var page: Page;
var tempSessions = [
    {
        id: '0',
        title: "Stuff"
    },
    {
        id: '1',
        title: "Stuffly"
    },
    {
        id: '2',
        title: "Stufferrs"
    },
    {
        id: '3',
        title: "Event 4"
    }
];
export function pageLoaded(args: EventData){
    console.log(JSON.stringify(tempSessions));
    page = <Page>args.object;
    page.bindingContext = new Observable({
        sessions: tempSessions
    });
}

I suspected that the first element of the list completely fills the gridLayout, however placing the border around it shows that this is not the case.

, , , "auto". - , .

* -. , , , = "col =", .

:

<Page xmlns="http://schemas.nativescript.org/tns.xsd" loaded="pageLoaded">
  <GridLayout rows="auto, *">
    <!-- Header -->
    <StackLayout row="0" cssClass="page-header">
      <Label text="Header" cssClass="page-title bold" horizontalAlignment="center" margin="15"/>
    </StackLayout>

    <!-- Sessions Views -->
    <ListView row="1" items="{{ sessions }}">
      <ListView.itemTemplate>
        <Label text="{{ title }}"/>
      </ListView.itemTemplate>
    </ListView>
