Language setting causes problem in LibreOffice

Hello,
I’m facing an issue which I can’t fully understand yet. Maybe someone has a tip for me how I can fix it.

After creating a new spreadsheet in NC and downloading the created file I’m facing the “maximum number of columns per sheet was exceeded” message in LibreOffice:

This problem only occurs when my language setting in NC is different from English. With English set as language I can create, download and open the file without any trouble.

Thanks for reading, I hope someone has an idea for me how to fix it without convincing all my users to change their language to English.
