If it's set to yes, then you're right that there should be CSVs created- it's just the most common cause of that issue, so it was a good first thing to rule out Definitely set it back to "Yes" before continuing.
Other common causes-
1) You've double checked what folder it should be writing to- ie if you have it set to write to DefaultOutputFolder, you've checked what that's set to that you're looking in the right place?
2) Do you have write permissions for the folder that you're trying to write to?
3) Are you in TestMode? (You'd be able to tell by the fact that rather than two buttons on the bottom left corner saying 'Start Test Mode' and 'Analyze Images', you'd have 4-5 saying things like 'Step', 'Run', 'Exit Test Mode'). Spreadsheets are not made in Test Mode, only in analysis mode.
If neither of those are the issues, you should upload your pipeline for troubleshooting.
