Bug?: Item Notes erased if making changes to stored document?

[UR user]

I assume this is a bug.

1. Store a Word document in UR.

2. Open stored document to edit.

3. While editing doc (e.g., hilighting), type in a few notes into "Item Notes" pane.

4. Close doc, and agree to save.

5. Saving the new doc wipes out the Item Notes.

Surprising behavior, and in my view a bug. There's no reason that the stored payload of a document item must be tied to the item notes.

Any thoughts? Thanks.
