The IMDB isn't allowing me to enter a year of birth for an actress.

The IMDB lists the day of birth for actress Jane Levy https://www.imdb.com/name/nm3994408/bio (December 29th) but doesn't list a year of birth.  I located her DOB on the California Birth Index at https://www.californiabirthindex.org/birth/jane_colburn_levy_born_1989_19294201 which is 1989.  However, when I attempted to either correct the existing date or add a new entry to provide the year of birth, it won't allow me to and just has a section for a place of birth (Los Angeles).

I've tried several ways around this, but it doesn't seem to work.  Can you tell me how to do this?  I haven't had this problem before.
