Created attachment 83490 [details] File with the problem and images with explanation. Problem description: I have a file with four sheets and in each one of it a few cells with a Conditional Formatting. I configured three different styles to be applied according to three conditions. I named Style One, Two and Three. I save the file as .xls and when I open again I have many styles with the name Excel_CondFormat that I understand which are created by a matter of compatibility with Excel. The problem is that these styles do not respect the original and when I change the format in Numbers it's not recorded, that is, it's making the change at the moment, but when I open the file this change is lost. I hope I was clear... the error exist from the version 3.4 the OpenOffice. Thanks, Bernardo. Operating System: Windows 7 Version: 4.1.0.4 release
