Number of participants reported online and in downloaded zip file do not match

URL of experiment: https://run.pavlovia.org/F.Poli/hide-and-seek-online-game-version-1/html

Description of the problem: on the experiment page on pavlovia, it is reported that 36 participants have been tested. However, the zip file only contains data from 26 participants. What might the reason be? How did I lose some of the participants?

Thank you very much for the help!
