I tried editing it in CAS but the dropdown menu won't move away from sisters.

Happened to me as well! Scary as it's identical to the old (old but currently unfixed) Get to Work bug where cloned sims become siblings to their spouse as well. Save File Ruiner because it's unfixable even with MCCC or uploading to gallery.
My guess? An issue with "sibling-in-laws" incorrectly being tagged as "siblings" in the game. If your spouse's sibling is your sibling, then your spouse gets tagged as also being a sibling.
See: Frida + Ulrike are CAS siblings with no parents. In addition to Ulrike's erroneous tagging, Frida should also be tagged as "sister-in-law", but she's tagged as "sister" instead. This is my guess as to the origin of the issue.
