Weird behaviour after 'add event' feature

[afroneth]

Hello,

After I executed 'add event desc/meeting startdate/12-12-2020 starttime/1000 enddate/12-12-2020 endtime/1130 recurring/1 week', there will be a wrong matching between the list of tasks of the left panel and the list of tasks on the right panel as described in my other issue. After investigating further, I tried to execute the 'done 9' command, and this results in a duplication of the same task on the list of tasks on the left panel. It seems that the 'done' function will simply result in more and more tasks being added to the panel on the left. As you can see below, 'done 9' added a new task labelled as index 10.
