Export to Excel: charge card for cost calculation missing

I planned a route in my web browser (Firefox), saved the route and exported it to an Excel file.
I opened the export file with Excel, it shows a nice table about the route (Location, SoC at arrival and departure, costs, charging time, distance, etc.).
But below the caption “Ladekarte” (english=charge card) the cells were empty.
I expected the name of the charge card, that the planner used for cost calculation.
