Hi Jacques,
if activity completion is enabled in your course, if you edit an activity you'll see an "Activity Completion" section. In there you'll see a "Completion tracking option" that can be configured to the following:
- Do not indicate activity completion -> Disabled.
- Students can manually mark the activity as completed -> The student needs to manually click the checkbox to mark it as completed.
- Show activity as completed when conditions are met -> The checkbox will be automatically marked when certain conditions are done.
I guess your activities aren't configured as you want to. As you say, modifying this value will erase all the completion data of that activity so all students will see it as not completed.
Kind regards,
Dani
