Notes value placed in a wrong column in the spreadsheet export

[Apfelstruhdl]

on windows 11:

Export project to spreadsheet (xls). Open it, see that there the last three columns are "Notes", "Web Link" and "Notes".
Notes of items are found in the "Web Link" column.
Import with a freshly started Ganttproject program returns an error:

"Something went wrong

The header contains a duplicate name: "Notes" in [ID, Name, Begin date, End date, Duration, Completion, Cost, Coordinator, Predecessors, Outline number, Resources, Assignments, Task color, Notes, Web Link, Notes]"

Unchecking the first Notes checkbox makes export working as expected:
