Why can't I delete a data module in Arbortext CSDB?

[shall-4]

I am using Arbortext CSDB for S1000D (4.2 M030) and do claim to be an expert.  I have been deleting DMs, importing and exporting them quite happily until now.  Two data modules refuse to delete.  When I right click and click Management thed Allocate Author and Reviewer are greyed out, which they aren't on all the other files.  When I try and do Delete DMC I get: "Not authorised to Delete DMC" even though I've deleted all the others around them.  Any ideas?  Thanks.

Sorry... I DON'T claim to be an expert!

I have more information about the issue.  It would appear that the Originator reference is in wrongly but when I try and change it:

Details - Show DMC Details - Originator (pick from list)

It comes up with:

CANNOT UPDATE DMC DETAILS IF STATUS IS QA REQUIRED OR GREATER

So I need to make the Status back to WIP, how do I do that?

Thanks
