Hi Tara,
The issue seems to be relarted to using a non Adobe Application used to fill the form, (E.G. Preview for MAC). Please ask your colleague to use Adobe Reader to fill the form and you would be able to see the responses.
However, in order to verify the same, please click inside any of the field, you do not see the responses filled in and you should be able to see the response.
Thanks,
Vikrantt Singh
