Empty rows in dataset

Hi all. In Limesurvey Version 2.0, I have the issue that often rows are not filled with information. The link send includes multiple SGQA-parameters to prefill a few questions. The empty rows have the same timestamp in the "date started" and "date ended" column and the prefilled information is not included. Does anybody experience the same thing or has a possible explanation for this?

Maybe some user look at first page and don't go next page.

That also happens sometimes, but in that cases the prefilled answers are visible in the dataset. So I assume it is something else.

Most likely they entered the survey without the prefill information. Depending on the email software the link including the prefill information might not be completely taken over when clicked because the email software will not completely mark it as URL.
I recommend sending HTML email invitations in such a case.

Best regards

Hmm. Well, if that would happen, users probably wouldn't quit the survey immediately (in the same second). Most of them would still answer the questionnaire. Could it be that search engine bots visit the survey-website?
