DEFECT: Story points show wrong totals when features expanded
Accepted answer
This is for questions and not a way to file defects. Use a PMR to file a defect or create a defect here Work Items - Change and Configuration Management .
Note: you have to provide a reproducible description, your post above will not be sufficient. There are also minimal standards that you should keep etc. provide version and other information. See How should I ask a question in the Forum if I want to receive useful answers? to learn about them as this is especially true when filing a defect or PMR.
FINALLY:
Especially with planning, my experience is that there is a lot you can do wrong in the process configuration and in using it, so it is very likely not a defect of the tool, but wrong expectation what should work and how.
For example PARENT/CHILD does NOT work across project areas. E.g. if a work item is in one project area and another is in another project area, roll up of story points won't work - but it will not tell you it does not.
