Time counted for sub-tasks is shown with Σ, but doesn't add to the day/month/year summary in the worklog
It's a super great tool so far, thank you so much :)
Thanks for reporting! I look into it!
Like this or different than this?

The behavior shown in the screenshot would be correct, as the parent task is just a container for the sub tasks and not an additional separate task.
Aha! In my case the sub tasks aren't shown on their own:

Ahh. So you did create "Team Aktionen" on Thu 7th? Then the calculation could still be correct if the time tracked on the sub tasks was for other days. It shouldn't show the parent task however. I have a look.
All 2:41 of Team Aktionen-sub tasks were recorded on Thu 7 – in my whole worklog there is not any sub task counting in the summary

(Website was created that day without working on it, the same way you mentioned it in the previous comment)
Hm that's ... interesting! I really would like to know what the data looks like to better understand the problem. Could you by any chance send me an export of it to [email protected]? Of course I totally understand if you think this too much personal data to share.
sent :)
Thank you very much again. I think I found the issue and also discovered a related one. I publish a fix soon.
