I was recently informed of Y-DNA propagation to a profile that I manage.
When I clicked through to the detail of this, I was informed that
"There is conflicting DNA evidence propagated from relatives in the family tree. To determine the source of the discrepancy, other males in the conflicting paternal lines should be tested for their Y-DNA. View a list of living males who can be tested for Y-DNA to resolve this discrepancy."
On investigating, it seems the only difference is the type (comprehensiveness) of Y-DNA test taken. One being Y-111 and the other Y-37.
On the Haplogroup information, these profiles match. This seems to be a bug.
