No new data when "downloading results"

I’m piloting an experiment online (Pavlovia) that I created in PsychoPy builder. Each time I run the experiment the number of “submitted” increases, but when i click “Download results” i can only see some old data files. The new ones apparently don’t get uploaded to Pavlovia. Is it because i don’t have credits and i’m in pilot mode? Each time I finish the experiment, a dialog about saving the data locally appears. That also puzzles me.

If you use a “Pilot” link then the data is only saved locally. To use a “Run” link you need a licence or credits.
