Index correction caused a mess in the 1850 U.S. census

I use the index correction feature nearly daily nowadays (because of whatever process it is that's adding the man's surname to the woman's in Hungarian civil registration indexes), so when someone posted about "Stalker" being indexed as "Slattery", I went and looked and agreed, and made the correction.
Ooops.
The search results look fine,
but trying to open the detail page for any of John's family members now goes to a page showing John's details.
https://www.familysearch.org/ark:/61903/1:1:M441-6DZ
Ditto for https://www.familysearch.org/ark:/61903/1:1:M441-6DD, https://www.familysearch.org/ark:/61903/1:1:M441-6DC, https://www.familysearch.org/ark:/61903/1:1:M441-6D8, and https://www.familysearch.org/ark:/61903/1:1:M441-6DH, except the "Attached in Family Tree to" person is different each time. The profiles' Sources tabs all have the "We are unable to display the record for this source. Please try again later" error message under Indexed Information.
All I did was change "Slattery" to "Stalker" on John's index entry. Really. The process made no mention anywhere of the rest of his family; I didn't so much as touch them until afterwards. My correction should not have caused this mess!
Do we need to warn people not to use the index correction feature on the 1850 U.S. Census?

I will pass this on to be researched. Thanks Julia!
