I have something strange when I am attempting to merge two children of the same parents.

PSHS-821 and PS4B-NWT. Joseph Edward Crouch has a well-documented life but on the 1911 Census he is marked as being a month old instead of 10 years old.

When I go to merge him using the new experience I get inconsistencies about the paternal grandfathers being different even though the parents are identical. I looked over things and do not see any way that there are separate paternal grandfathers. I think there is a data error somewhere. I thought I would post here instead of forcing the merge.
