Repeatable fields do not currently work with signature, image or field upload fields. If you are not mapping one of the incompatible fields we would need to see the form and field map layout to further troubleshoot the issue as the current version of the function has been tested and found to be working as intended.
If possible, please export the field map layout and attach it to this form, we do not need to login at this time.
We remain at your service.
