Hi Adam, I've not heard of anything like that. If you open the exported file and look inside the XML, has the comma been replace with a semi-colon? If not then it would suggest the import logic is making the change. So after importing, if you export again and look at the XML, what do you see? And after correcting the error, if you export and then import again, what happens?I think it might be worth raising this with our Support team - please provide them with example before and after XML, and details of your BP version/OS version/language and locale settings etc.
