RQM 2.0 -'Save Error' for Work Item in imported test case

Initially I imported the test cases as documented in the Tutorial - Install Sample Data.
I then executed the steps documented, and I added a new requirement to the test case. (Chapter 3.1 - Step 7.)
However, when I tried to create a new Work Item and then save my change, I got the following error
"New Task-Quality can only be created if the TestCase is in Draft State"

I notice that the State: displayed in the test case = "com.ibm.rqm.planning.common.new",
so I checked the sample xml file I imported and I see the line containing the state =
<state>com.ibm.rqm.planning.common.new</state>
I modified the file as follows:
<state>Draft</state>
re-imported it and attempted again to create a new Work Item.
Unfortunately I still get the same error - even though the State now shows "Draft".

I then attempted to import my own test case, creating it using the xml format shown in the sample and setting the state = "Draft"
ie. <state>Draft</state>

However, when I try to create a Work Item I get the same error, even though State does = "Draft".

I also notice that the Action drop-down list does not contain a "Ready for Review" option
unlike the Test Cases I manually created from scratch.

Does anyone have any idea what might be causing this problem?

Come on!!
I need to the same.

Please, some one put format of XML for import in RQM.

Thanks
