The Old and New Source Linker are interpreting Index differently
I don't know if this has been reported before or which one is functioning incorrectly, but I was doing some comparison of the old and new source linkers and found an example of them displaying differently.
Source linker: https://www.familysearch.org/search/linker?ark=/ark:/61903/1:1:6F3Q-5NWY&id=GPQZ-9HN
Switching between the old and new versions you can see that in the old source linker the father's record displays against the father's profile probably because it has been attached to that profile. However in the new source linker the father is shown under Others On Record, probably because the index does not specifically label him as the focus person's father even though the record has been linked to the profile.
It seems that it would be important that once the linking was set as correct that that would override what the index claimed. This does work properly when Eileen is set as the focus person. Even though Carl is still not designated as her husband in the index, he does line up properly.
