Getting an Error on Mobile while tool works online

Hi Kal,
Top of the day to you.

Just yesterday, i had designed a tool which i deployed online and was doing fine on the online version. When i uploaded the same on mobile, i got the following error

“Repeats in “field list” groups are not supported. Please update the form design to remove the following repeat from field-list:” I have attached the picture here for reference.

I would really appreciate your help with this.

Thanks a lot

@babajide_oluseyi, would you mind validating your XLSForm through this online validator to see if three are any syntax issues?
