XML Export not work

Unfurtunatly with Joomla 5 and the Balbooa Forms 2.2.1 the XML export is not working. When I try to export it, nothing happens.
If I export the csv, this works, but I can't import the CSV to an excel that I can make a nice table of the data, because the excel cant resolve the format.
Can you help me?

Thank you.

Best regards
