My married sims are showing up as sisters now

I have a married female couple that all of a sudden are showing up as sisters AND spouse. I have tried to edit the relationship in cas.fulleditmode, nothing works. I think it may have something to do with the pop up for the "close" family dynamic, but I have removed that dynamic and it is still showing them as sisters... No clue how to fix it and I've played with this family for so long and they have three kids.
