Issue on import with the option total cost and total load option switched on

I switched on total cost and total load options in the settings -> spreadsheet menu.
When I do an export to excel Xls,… it now shows 2 total cost and total load headers in the resources section,… preventing an import.
Might be a bug ?
Since it’s already in the original export I will switch it back off.

Thank for reporting! This must be after export + import + export cycle. I submitted a bug report:
