The DeleteColumn appears to work in memory but when the package is saved following a delete column the file is corrupt and so is the in memory version of the associated worksheet.
I've attached a file that contains three NUnit tests that demonstrate the problem. Hopefully you can correct this ASAP or suggest a workaround. Let me know if I can help with this further as it is now holding me up.
