Improve critical path

The Gantt view has been added and there is an option to highlight the critical path, but I still find the display of the critical path unsettling.

In the figure below,
The critical path is highlighted as “1(1)-2(2)-4(3)-2(4)-1(5)”.
However, according to my understanding, “1(1)-2(2)-5(31)-2(4)-1(5)” is the critical path.
