Data loss when downloading survey data in excel while there in pavlovia

Hi
I have a survey and when I go to download the data, the resulting csv only shows the first row of data. When I check on each participant the data are there and similarly when I open it in notepad but when I open it in excel, those rows are empty. I have tried opening the csv in r and they are similarly empty. All that are reported are surveyID, repsonseID, experimentId, sessionToken and participant. The data are definitely there - they come up in notepad.

Any ideas?

Thank you!!

Please could you PM me the data file so I can take a look?
