It seems like the game will prevent the choice one the romantic relationship bar has been set in.
The only thing I can suggest is to save the sims to My Library, set them to siblings, and re-add them back. This will destroy the relationships and the inventory, but the skills, traits, careers etc should stay. If you can find a way to completely destroy the relationship so these sims don't know each other, you'll either have to accept it or do the My Library/Gallery method.
