It appears that no one has submitted a mini-bio for her page. In such a case, the system automatically generates one based on data added to other areas. It will, even though the guidelines says you should not list titles from filmography because it's redundant, use titles it selects from the "known for" feature (see: "Known For" Credits Frequently Asked Questions).
It's not possible to simply change one, or add one, title to the system-generated bio. To change what appears in the section, one would have to completely replace it by authoring a bio that adheres to the Mini-Biographies guide/rules.
