In this case, I suspect it is a switch that you did activate that you should not have. (or maybe it was the default setting, not sure.)
Based on the image you shared, you have set the assignments group to be zero percent of your final grade. Which means none of the assignments in that group are counting towards the final grade.
Check your Assignment group weights. If you simply want to add up all points for course activities without any group weighting, uncheck the box for Weight final grade based on assignment group.
If you do want to weight grades, you will need to assign each group percentages to total 100.
