Created attachment 116294 [details] easy way to reproduce the bug In a Calc in xls file format, the condition of the conditional formatting of a cell is changed after the file is saved and opened again. How to reproduce : Open a new calc enter "aa" in cell A1 enter "aa" in cell B1 define a conditional format of cell B1 : if cell content is equal to cell A1, get a style (green color in my case). Save and open again. If you now look at the definition of the conditional format, A1 is changed to sheet1.A1, which is still correct. Save and open once again; now the error appears. If you now look at the definition of the conditional format, sheet1.A1 is changed to $#REF!.A1, resulting in a all ways FALSE condition. This problem only appears with xls files, not with xlsx files neither with ods files.
