[closed] Problems creating work items specified by a template

Hi,
I am currently experiencing a problem when trying to create work items specified by a template. Let me give you some details on the configuration first:

Workitem Name: Defect
ID: defect
Category: com.ibm.team.workitem.workItemType
Aliases: bug
>> This category has specific required attributes (e.g. Phase detected, which is a custom attribute)


Workitem Name: Task
ID: com.ibm.gbs.workitem.workItemType.action
Category. com.ibm.gbs.workitem.workItemType.action
Aliases: work item, workitem, item
>> This category has specific required attributes (e.g. Phase detected IS NOT required here)

When I try to create a plan using a workitem template, I get the error: "Cannot create work items specified by template. 'Save Work Item' failed. Preconditions have not been met: The 'Phase Detected' attribute needs to be set".

It seems like it is trying to create tasks but using the required fields defined for the defect's category. I confirmed that by removing the Phase Detected attribute from that category.
What should I do to fix this problem?

Thanks in advance,
