On the Issues Search page in JIRA, when using the Column Chooser, there are duplicate options for the "Time Tracking" fields of: Original Estimate, Remaining Estimate, Time Spent.
One of the versions of each field has the "Sum" icon by it.
We haven't seen any difference in the values produced by either field.
So. . . why are there two different versions of each field (Sum and Regular), and what is the difference, if any?
