Can indexed records be re-indexed when a problem is found?
I have an ancestor and her family listed in a 1880 US Census record from Iowa (https://www.familysearch.org/ark:/61903/3:1:S3HY-6G14-X8W?i=17&cc=1438024&personaUrl=%2Fark%3A%2F61903%2F1%3A1%3AMDJP-F2L ). An indexed record was created from the census record in which 2 separate households (one of them being my ancestor) were merged into one (https://www.ancestry.com/discoveryui-content/view/32329780:6742 ). This has caused much confusion for our family's research efforts and I'm assuming for others as well. The indexed record shows the husband of the Twyford family as the Head of Household and the mother of our ancestor's family (Jane ??Faer, which by the way, was also indexed incorrectly. Her married name should be spelled Miler.) in the designated space for his wife, with all other members of both families shown as members of the same household. This problem causes further confusion when family members have tried to merge this record with other legitimate records, especially when the members of each of the indexed families have similar first names.
My question is, can indexed records be re-indexed when a problem like this is found? Who would I contact to make the changes if it is possible?
