There is a problem with the excel file from KOBO

[Vlad_Dn]

Hello.
Could you please advise me
What can be the error shown on the screenshot?

The data is downloaded from KOBO and then we open the downloaded Excel file and this window pops up.

And then the following window pops up.
I can’t understand what the problem is. There are no formulas in the form.

@Vlad_Dn, have you validated your XLSForm through this online validator to see if there are any syntax issues in your form? BTW, could you also let us know the server you are using?

This questionnaire has been working for a very long time. This window appeared recently.
