Exporting Data: Date of last editing instead of date of the expense.

When I export my expenses to an xls file, the second column (dates) stores the last date in which an entry was edited. However, the entries are sorted by the date set in the app. (The same way the expense log is sorted). Is this behaviour intentional? It confuses me a bit, in my opinon it would make more sense to store only the set date...
