Filtering comments in pane make comments disappear from document

Hi all,

Just notice today that when I filter comments (for example stamps) in the comments pane then all the other comments like highlight and text disappear from the document itself and not only from the "comment pane". 

If I remember correctly the filter comment use to work only for filtering on the pane itself and not on the document.

Let me know if you understand what I mean.
