Remove the string "Hours" when creating a report..

Does anyone know how to drop the Hours string that gets added to Actual Hours when creating a report? i.e. 10 Hours.

I have a report that has the actual hours, planned hours, and estimate at completion. I export this to an Excel spreadsheet where I do comparisons to find tasks/projects that are in trouble. I am tired of having to run the macro that does a find/replace to remove the "Hours" string from the worksheet so my Excel calculations function correctly. I do not understand why it even puts in the "Hours" string on every row since the column heading is Actual or Planned Hours.
