How does one Change the default Chart for a Sprint Release Plan

Hi,
I have two separate RTC projects that were both created from the same process template.
If I go into Project A and run my Sprint Release 1 plan, then click on the Charts tab, the default report is "Work Items by Type"
However, if I go into Project B and run my Sprint Release 1 plan, then click on the Charts tab, the default report is "Burndown"
I found an RTC Work Item that several people have asked this question, but I have not found any answers online or in the manuals. I am assuming that someone made a change to the Project Template to get a different default report, but I cannot find where to make this change.
Both projects are pointing to a Parent project to get their process from, so I am really baffled by this one.
Please let me know if you have run into any solutions.
Thank you,
Mike
