Annotation doing weird things

Hello folks. I was reading a pdf within DT3, and chose to mark a point in the text by choosing annotate, then oval. I didn’t click on anything else. Suddenly every link in the document was greyed out, and I’ve no idea how that happened. Thoughts?

While editing annotations PDF link annotations are marked like that to easily spot & select them (e.g. to select, edit, move or delete them)
