Can't get MeteorListView scrolling to work

[814k31]

Tried following the example but had no success Whenever my MeteorListView renders it refuses to allow scrolling Is it something obvious I'm missing?

Also ListView has been deprecated

"dependencies": {
    "react": "^16.3.1",
    "react-native": "^0.54.4",
    "react-native-meteor": "^1.2.0",
    "react-router-native": "^4.2.0",
},

    // Scrolling Doesn't Work
    renderItems() {
        return this.props.itemsReady ? (
            <View style={{flex: 1}}>
                <MeteorListView
                    enableEmptySections={true}
                    collection="items"
                    contentContainerStyle={{flex: 1}}
                    options={{ sort: {dateCreated: -1}, limit: 20 }}
                    renderRow={(item) => {
                        return (
                            <View style={{ marginTop: 5, marginBottom: 5 }}>
                                <Text style={{fontWeight: 'bold'}}>{item.name}</Text>
                                <Text>{item.description}</Text>
                            </View>
                        );
                    }}
                />
            </View>
        ) : <ActivityIndicator size="large" color="#00ff00" />
    }
    // Scrolling Does Work
    renderMockListView() {
        return this.props.itemsReady ? (
            <View style={{flex: 1}}>
                <ListView
                    enableEmptySections={true}
                    dataSource={ this.state.listViewData } // Gets set to the Same data when the collection is ready
                    renderRow={(item) => {
                        return (
                            <View style={{ marginTop: 5, marginBottom: 5 }}>
                                <Text style={{fontWeight: 'bold'}}>{item.name}</Text>
                                <Text>{item.description}</Text>
                            </View>
                        );
                    }}
                />
            </View>
        ) : <ActivityIndicator size="large" color="#00ff00" />;
    }
