In the panel for "pdf comments" you can set a filter to show only some types of comments. If you open this panel, all "comment type fields" are unselected – although they can all be seen in the document (screenshot 1). This is a mistake. All the fields should be selected at this point.

If you click on one or more types, only these types will be displayed in the InDesign document. Correct behavior now. (Screenshot 2)

Tested with InDesign 2026 21.1 and 2026 Prerelease 21.2
