Picker close when screen orientation changes

[akankshaldots]

Picker is getting close when screen orientation changes even after setting android:configChanges

 <activity android:name=".activity.DashboardActivity"
        android:windowSoftInputMode="adjustPan"
        android:configChanges="orientation|screenSize"/>

   val today = Calendar.getInstance();
    val builder =  MonthPickerDialog.Builder(mContext, { selectedMonth, selectedYear ->
        run {
            mSelYear = selectedYear
            mSelMonth = selectedMonth
        }

    }, today.get(Calendar.YEAR), today.get(Calendar.MONTH))

    builder.setActivatedMonth(mSelMonth)
            .setActivatedYear(mSelYear)
            .setTitle("Select Month and Year")
            .build()
            .show()
