Case folder in collections workbench doesnt hold history of Notes

Summary:

Hi Team,

I created a case folder in collections workbench including 3 invoices (Invoice 1, Invoice 2, Invoice 3). I entered notes against this case folder (Case 1).

Then I included Invoice 1 under different case folder (Case 2). However, the notes which I entered against case folder 1 for invoice 1 is no longer visible anywhere. Where can i find the history of notes for Invoice 1 when it was under case folder 1.?
