I'm experiencing some strange behavior when saving a workbook that has pre-defined conditional formatting. Attached is a simple console application that opens Book1.xlsx, saves it to Book2.xlsx. Book1.xlsx has a single cell with Conditional Formatting applied:
Cell Value = 1, then Green Else Red
After running the Console App, the rule in Book2.xlsx shows Red for both conditions:
Cell Value = 1, then Red Else Red.
I'm using version: 220.127.116.11 with Visual Studio 2010. (Note: This behavior existed for version 18.104.22.168 too).
