Ha, another sneaky bit. Your file has some columns that are longer than others. This is the real reason that some columns in your 2D array has trailing zeroes. It's because LabVIEW will pad shorter columns with the default value (0 for numbers) in order to force all 2D arrays to be rectangular.
You can deal with this issue in many ways. See what you can come up with and post back if you get stuck. I'm about on my way home but I'm sure someone else will chime in if you're looking for help tonight.
