I'm using RTC 3.0.1.3 and I have exported stories and risks from one Project Area and simply imported those workitems into another Project Area with same CSV file. Then, I found a problem.

For example, story have attribute call "story points" and risk have not, but when I view a workitem that type is risk in Eclipse Client, I found "story points" is listed in customization tab page. I think it means this workitem may have "story points" implicit

Also, when I click "Check attributes usages in repository" and show the affected item, those workitem with attribute that isn't belongs to it will be listed.

I have try to "Synchronize Attributes" in those workitem, but totally no use wtihout any error infomation and those workitem still listed in affected item list.

I really need some help to learn how to fix those workitem and remove those unexpected attribute.

thank you for your kindness!
