Gender-neutral family relationship descriptors

Today I was playing with CAS a little bit and made two sims that matter for this bug. One is transgender female with she/her pronouns selected. The other is her child who is nonbinary. The mother shows up as the child’s father and the child shows up as the mother’s daughter. This does not fit with either of their pronouns nor the inclusivity feature added to make it partner, sibling, and spouse. I don’t know if this was a bug or is intentional but it feels wrong.
