chosenLabel property is not reset on new apply event and stores value of previous selection

How to reset chosenLabel on every new apply event?

Here is a use case.

Given DateRangePicker settings for reset range:

<DatePicker
    id="actDate"
    startDate={moment()}
    endDate={moment()}
    dateLimit={null}
    onEvent={this.onEvent}
    ranges={{
        'Tomorrow': [
            moment().add(1, 'day'),
            moment().add(1, 'day')
        ],
        'Next 15 Days': [ ... ],
        'This Month': [ ... ],
        'Next Month': [ ... ],
        'RESET': [ ... ]
    }}
/>

And onEvent method looks like this. Look at picker.chosenLabel.toLowerCase() line:

onEvent = (ev, picker) => {
    if(ev.type == 'show' || ev.type == 'hide') return;
    let reset = false;
    if(picker.chosenLabel.toLowerCase() == 'reset') {    <== here
        reset = {reset: true}
    }
    this.props.dispatch(sortByDate(reset))
}

Steps to reproduce the issue:

1. Click any predefined ranges after the datepicker loaded. Suppose it was RESET.
2. Now make a custom selection of date. You will see that chosenLabel equals RESET. The property for some reason stores the value from previous selection. It is not logical. I'm making a brand new custom range selection, but the property is equal previous selection. This is what I don't expect and my code on custom date selection gives wrong result because of that.

How to reset chosenLabel on every new apply event? Or at least how to set chosenLabel to null on custom range selection, so that it is reset from previous value?
Or even more specifically:
How to figure out that a custom date range is selected at the moment, not a preset? Because as you just saw, checking chosenLabel gives wrong result.
