Example; In my son's [Hough-3018] tree he shows a ydna link to [Hough-2995] which is his great great grandfather. It is identified graphically with the blue triangle (male lineage) behind the pink one, Whereas mine displays nothing at all. Both profiles are set to "confident". If I go to the pull down menu under any male ancestors i.d., and I select "relationship to me", it shows everything as it was. When I initially took the yDNA test it fully propagated the male line without a single generational gap. Now it has changed to displaying only two people. That's what makes it confusing.
