We are aware of the issues with the US 1850 and 1860 census as well as the UK 1871 census producing strange results in search and having bad links in online trees.
We are working on resolving it as quickly as possible.
Thank you for your patience.
Update: The issue has been resolved, links and search on these data collections should be working normally now.
