"This Record Has Been Removed" and "410 - Record removed" issue for select members of a family
I just came across an issue where, over the course of a few days, several individual records (or data entries?) on one sheet of the 1900 US census were removed. The head of household's record still exists there but records or data entries of the wife and children are missing. When I click on a link to the source that is for the head of household, the record details screen comes up. When I click on a link to the source that is for the wife's record (a link that worked fine a week ago), I get a page that says "This Record Has Been Removed." In the source list on that individual's details page, there is red text saying "!410 - Record removed."
I can still use the source since I can see the original image, but this means it isn't searchable for people looking for those individuals. It seems that all the other people's records on that census sheet have records with the exception of the last few on the sheet (the people I've mentioned) and the first person on the next sheet (which is the final child in the entry for the household I am interested in). I was at first concerned that I had done something during my research (and some edits to the records such as dates, name spellings) but I can find evidence of changes I've made to the one existing record. I can't find anything (revision history, activity log, etc.) that indicates I could have deleted an entire entry in an indexed record.
Here are relevant links so you can see the example: https://familysearch.org/ark:/61903/1:1:MSZY-2LT (works) and https://www.familysearch.org/ark:/61903/1:1:MSZY-2LY (doesn't work)
