Ingeborg Thrandsdotter, av Sula - About Text

The first paragraph of the About text explains that Thrand of Sula had two daughters named Ingeborg and not to confuse this Ingeborg with her sister.

This profile does not currently have a sister.

This glaring inconsistency raises the question, has the sister been unintentionally disconnected or is the author of the note mistaken? If the later, why is the text left in the About to confuse users? If the former could someone assist by reconnecting or at least tagging the sister in this Discussion and I will reconnect.
