Accepted answer

This behaviour is caused by the data-gropuing feature. You can disable the feature:

"plotOptions": {
    "area": {
        ...,
        dataGrouping: {
            enabled: false
        }
    }
}

or control anchor behaviour:

"plotOptions": {
    "area": {
        ...,
        dataGrouping: {
            anchor: 'end',
            lastAnchor: 'end'
        }
    }
}
