I would like to contribute to the same topic, however I can provide screenshots for the incorrect display in the analysis of tags in the bar display and hope that this will enable you to understand the description of the error.
The examples come from two completely different computers, each with independent databases.
The error can therefore be described as reproducible. In order to be able to distinguish between the two examples, one is shown in a dark Windows design, the other in a light Windows design.
Please note in the respective examples that the number of hours of the Tag bar display in each case goes beyond the number of hours of the tasks and thus the time periods for each individual day fall completely out of the actual time frame. To ensure a better comprehensibility for you, I have added markers and arrows and put a comparative display with the length of tasks against it.
Here is the example of my working computer:
Here is the example of my private computer:
Another problem is the fact that sometimes the bar display for tag analysis does not work. Then only a restart of the program helps. - Not good ... I think you have heard / read this several times in this forum.
If there are any questions about this, please don't hesitate to contact me.
I'm looking forward to your reply.
Thanks in advance for your effort and best regards
