Yes, it is a known issue. There was an announcement, but I believe that announcement was taken down when the developers thought they had the problem fixed.
@N Tychonievich can you please assist?
@Douglas McPhaden this thread from December will give you some background. https://community.familysearch.org/en/discussion/111793/a-gremlin-in-the-1900-us-census-kearny-new-jersey#latest
@Douglas McPhaden, thank you for reporting this problem with the 1900 United States census. As @Áine Ní Donnghaile indicates, this is a problem that we had hoped was resolved; but clearly we were mistaken. In addition to the link already suggested, you may also want to look at the comments provided here: https://community.familysearch.org/en/discussion/116171/1900-united-states-census-problems#latest
We are making the engineers aware of these problems as we find them. Thus, I will forward your information so that they can include it as they work to fix this problem. From your post, I have all the information I need to forward this problem. We hope for your patience, as the engineers are, apparently, currently working to resolve these issues record-by-record.
We apologize that you, and others, are having this problem with the 1900 United States census and, with you, are anxious to see it resolved.
