I have tried to use org-clock-display (
C-c C-x C-d) in order to know how much time I have spent on an activity, which is broken down further. The first three outlines won't have their time spent accounted for, as shown in the image below. From module 4 onward everything works fine.
I do no know how to debug this, and have tried to check if the structure of the time appointments are correct, which by visual inspection they seem to be. Is there something I am missing or that could help me to debug this issue?
