Hello Brandon,
I foundthis topic and followed as what Ismael said:
https://community.esri.com/thread/189915-repeats
"If you want to have a quick look at a survey with a repeat, do the following:
In Survey123 Connect, select New Survey and pick the Community category, then select the Polio survey."
I tried with this XLSForm, I didn't modify it just take and used it, everything was going fine until I needed to edit de survey.
I client ask us about this issue and we did tests about it.
We replicate the same issue.
Thanks and regards
