KoBoToolbox: Grouped Fields Not Capturing Data

I have multiple grouped fields (some nested) that are conditional based on an earlier question. Any field outside of these groups functions as expected. All fields within every group do not. Most are text fields. None are required. The Data View only displays “[object Object]” (see attachment) for any field that contained data, and when I view the full submission record, the fields are blank. Any idea what’s going on?
