The file used to reproduce the bug

When I use HSSFCell#setCellFormula to modify the formula in a cell, if I just adjust some cells in the formula, e.g.for AVERAGE(A1:F1) to AVERAGE(A2:F1), HSSFCell#setCellFormula will be wrong modify the row of the second cell to the row of the first cell, but the first cell will not be modified!

before fixing:
Expected value:
Actual value:

Below is the test code to reproduce this problem:
    public static void main(String[] args) throws IOException {
        Workbook workbook = WorkbookFactory.create(new File("E:\\Average.xls"));
        Row row = workbook.getSheetAt(0).getRow(0);
        Cell cell = row.getCell(6);
        System.out.println("formula before modify:" + cell.getCellFormula());
        System.out.println("formula after modify:" + cell.getCellFormula());

The Average.xls in the attached file.
