Search - Records can't find a particular index entry

There are two deaths indexed from image 7 of film 4855621, and they're both correctly there on the Image Index tab, so if you start with the image, you can bring up the individual index entry pages with no trouble.
Rutkai Anna: https://www.familysearch.org/ark:/61903/1:1:6V1G-8VKG
Pozczolka Antonia: https://www.familysearch.org/ark:/61903/1:1:6V1G-NPL3
However, in the other direction, there's no way to get to poor little Anna Rutkai's death record. No matter what search details I try, if I tell Search - Records to look on this film, it cannot find Anna Rutkai. For example, if I tell it to look for Anna with any surname starting with R, it comes up with a single entry for a mother named Anna Rózenberg (https://www.familysearch.org/search/record/results?count=20&q.filmNumber=4855621&q.givenName=Anna&q.surname=R%2A). Yes, I've even tried it with the names reversed (given name Rutkai or surname Anna), and yes, I've tried it with just her parents. It can't find them, either.
The other entry on the image comes up without any trouble (https://www.familysearch.org/search/record/results?count=20&q.filmNumber=4855621&q.givenName=Ant%2A&q.surname=Poz%2A).
Does anyone have any idea what's going on here?

Clicking on the record for Rutkai, Anna , I then clicked on the link for the Digital Folder Number
004855621 which as far as I am aware should give you the records for this microfilm. I then filtered death by year 1899 to give a smaller database.
Going back to the record for Rutkai, Anna I then advanced to the next page consisting of two records for Taubek Anna and Karafiáth Anna
Although I could see a record for Karafiáth Anna in "my" subset of records, I could not see a record for Taubek Anna .
On this extremely small sample perhaps the first/top record on each digital page is being transferred to a different database, or is perhaps being "lost" due to some coding error?
