Record is not showing on my tree after I indexed it

I found this record but one name was wrong and the others were missing:

https://www.familysearch.org/ark:/61903/1:1:XQ7B-YY92?lang=en

So I edited the names on the original file:

https://familysearch.org/ark:/61903/3:1:3QS7-89Q3-MCW4?view=index&personArk=%2Fark%3A%2F61903%2F1%3A1%3AXQK1-7ST6&cc=2046896&lang=en&groupId=M9H4-2KQ&action=view

But now, it seems like I broke the original file and I can't attach the the names i added to the original document to my family tree (I mean I can, add it as a source, but it doesn't prompt the linker) Also the names in the original file are also showing an error message: "Unable to show if this record is attached to a person in the tree."

And the Indexed record is still wrong, it didn't change.

I'm new to family search, please forgive me if this question was already answered or if its not allowed, please delete it.
