When using the survey123 mobile app the select one doesn't have any values after creating the first record. this only seems to affect the mobile app and the web version works without issue.
Have I set this up correctly?
Can you attach your survey xls so I can take a look?
But using reserved words (start and end) as question names is likely to be one of the problems. Also you don't need give the end of repeats names or labels - only end repeat is required.
