It looks like the behavior you are referring to is related to the 'select_one' questions in your survey. Please take a look at the previous GeoNet forum thread, which highlights the following...
"This is a known issue with select_one questions. The data itself is written as the name column and a domain is created to so that the labels seen in Survey123 will be seen in ArcGIS Online; in all but file geodatabase exports, ArcGIS Online provides the code (choice names) instead of labels. You can export the data with the labels via ArcGIS Desktop tools - see Problem: Coded value domain descriptions are not maintained after exporting data"
Please let me know if this is not related to your question.
