Sessions vs. reserved credits vs. participant data

URL of experiment: l720_projet_final [PsychoPy]

Description of the problem: Hello, I am new to using PyschoPy and Pavlovia. I’m confused (and concerned) about data loss in my experiment. It says that I have 12 sessions, 8 reserved credits and 0 completed, and yet when I download my data I only receive 3 csv files and only 1 is complete.

I’m unsure why this discrepency might be and how to fix it.
