Cannot add or update Gender data

I recently completed a cast list for a TV episode, (submission #240827-163250-490000).  One of the people in the cast was a woman playing a female role, and as such, was submitted to the 'actress' category.  However, even though the contribution was approved, that person was added to the 'actor' category instead.  (see cast order #26)

I attempted to move the actor credits to 'actress' by assigning the correct 'gender', but the submission interface does not allow it:

This person appears to identify with 'female', so I'm not sure why this change is blocked.  Their page shows this self-verified information:

Their Biography contains many she/her terms:

And their photos look to be female:

On their casting site (not IMDb), the photo looks female:

and the "sizes" detail on the casting page also indicates female:

So the question is, why are the acting credits in the 'actor' category instead of 'actress' and why can't they be moved?

I have intentionally left this persons name out of this message so as not to draw unnecessary attention to them. The staff can find who this is via saved submission #240830-143659-340200.
