Not all icons are shown about react-native-timeline-listview

[LongicornYu]

The code is the same from the sample.
Any idea what might be the issue? Thanks
<Timeline style={styles.list} data={this.state.data} circleSize={20} circleColor='lightgray' lineColor='rgb(45,156,219)' timeContainerStyle={{minWidth:52, marginTop: -5}} timeStyle={{textAlign: 'center', backgroundColor:'#ff9797', color:'white', padding:5, borderRadius:13}} descriptionStyle={{color:'gray'}} options={{ style:{paddingTop:5} }} innerCircle={'icon'} onEventPress={this.onEventPress} separator={false} detailContainerStyle={{marginBottom: 20, paddingLeft: 5, paddingRight: 5, backgroundColor: "#BBDAFF", borderRadius: 10}} columnFormat='two-column' />
