This looks related to an issue we had related to support for Entities from groups and repeats: Multiple entity behaviour - difference observed between ODK central and ODK Collect We thought we had a complete fix but it appears that may not be the case. We are investigating.
@Chimwemwe This is an issue with the conversion from XLSForm. So if you have an XForm that's working in your test environment, you can download that and upload it to your production instance and that should give you the behavior you want.
