What's the purpose of the RISE checkbox lists?

I used this feature recently and made it a SCROM , however it only allows the user to tick off the list in the moment, say if he was to exit course nad then return back or there was a connection issue and he was to open course again, all his check marks are lost and not saved. Strangely, it doesnt save changes even is you go to the next section and then come back Lesson/Section 1. As far as I know this check box option should be saved so when you do check it, you can complete the incompleted boxes. If we are using checkboxes as click boxes to complete a task we must be able to have these checks saved. Or maybe not have check box under Lists and have a checklist feature and a complete seperate option that enables us to save these intereactions while on the go.
