After testing, it looks like I'd be safe to assume that you have added choices to your choice-list after the initial survey creation/publishing, and then republished?
If this is the case, the behavior that you are seeing is likely related to the fact that Survey123 Connect does not update the domain after the initial publishing of a survey. It looks like the choices that you added were choices '27' and beyond.
[Revised from original] There is a way to manually update the domain by navigating to the Item Details page of the feature service and clicking on the Fields view. From here, you should be able to click on 'Installer' and 'Second Installer' and add the values to the domain. So, you would add the Code '27' and Label as <installer name>, etc..
In the meantime, I will add your experience to an existing discussion in our backlog related to this behavior.
Best,
Brandon
