setSelectedDateRange crash with Fragment CalendarSheet not attached to a context

[codebyzen]

Have simple code:

button2.setOnClickListener {
            calShow(this)
        }

and fun for calendar create and show.

fun calShow(ctx: Context){
        val simpleDateFormatRangeStart = SimpleDateFormat("yyyy-MM-dd", Locale.ROOT)
        simpleDateFormatRangeStart.format(Date())

        val simpleDateFormatRangeEnd = SimpleDateFormat("yyyy-MM-dd", Locale.ROOT)
        simpleDateFormatRangeEnd.format(Date())

        val calendarSheet = CalendarSheet().build(ctx) { // Build and show
            title("calendarTitle") // Set the title of the sheet
            maxRange(3650)
            calendarMode(CalendarMode.MONTH)
            selectionMode(SelectionMode.RANGE)
            setSelectedDateRange(simpleDateFormatRangeStart.calendar, simpleDateFormatRangeEnd.calendar)
            displayButtons(true)
            onPositive { dateStart, dateEnd ->
                Log.d("***", dateStart.toString())
                Log.d("***", dateEnd.toString())
            }
        }
        calendarSheet.show()
    }

In this case if quick tap on button (button2 in my activity) for several times i got crash with this error:

Clarification. It happen only when i tap on semi transparent background (cancelable is true) at the moment when calendar is not yet shown completely.
