Bug : When exporting to excel the date format

Bug : When exporting to excel the “begin date” and “end date” switch from the format date to general.
This always starts at row 23.

Expected behavior :
When exporting the begin and end date fields should be set to the format → date

Current behavior :
When exporting the begin and end date switch from the date formate to general format.
This starts at row 23.

Attached printscreen :

It always works fine in my tests. There is no magic number, all date cells have date format. However, it is possible that it depends on the system locale, date format or software version (I tested in LibreOffice and Google Sheets, but not in Excel).

Please share your project file, log file (Help > View log) and let us know in what software do you open the result and is it the same if you open it in other software which supports Excel format.
