Thank you for the quick response.
The "Allow... update responses with one token" setting you mentioned was previously set to "No". I changed it to "Yes" and do not see any change to the behavior described in the original post. The participant receives the invitation, clicks the link to execute the survey, completes the survey, and the administrator receives an email that the participant has completed the survey. The "token summary" counters increment, showing the invitation has been responded to by completing the survey. The "response summary" counters are unchanged. When I display the responses, the only responses shown are the test responses I entered using dummy tokens, via the "data entry" facility.
Additional information: In the notification email sent to the administrator upon completion by the participant, clicking the link to "see the individual response" results in a "Bad Request" webpage with the following message:
