Editing Indexed Records is a Big Mess Right Now.
I don't know how or who to notify that the editing feature of indexed records is a huge mess right now. The editing feature is not editing the record you are in but rather editing the head of household record. It has created a numerous list of the same edits by multiple users and and crossing the data between edits to other persons in the indexed record.
Please look at the United States 1900s Census https://familysearch.org/ark:/61903/1:1:MM5P-FXN. Specifically ID# KWZP-YP7 & KWJZ-3MS and all their children. It is not listing the proper relation to head of household nor gender etc. It's just mixing all the data fields up.
