Hi Swapnil,

Yes, this is the current behavior. If you are importing a shared list from CCH, you need to add previously downloaded authority documents in it along with newly added documents.

Here is the documentation on it: 

https://docs.servicenow.com/bundle/sandiego-governance-risk-compliance/page/product/grc-ucf-import/task/download-a-shared-list.html

We are working on a solution which will remove this dependency and would allow you to import multiple shared lists as well as import documents without adding previously downloaded documents. It is on the roadmap for next year.

Thanks,
