century-accurate date converted into random year

[Cembranus]

Hi! As per image, for Thusnelda, whose birth wikidata places in the 1st century b.C., the game sets it in the year -100 (not possible since she died on 17 a.C.). Same happened for another person born on the 1st century a.C., the game set the date on the year 50.

"Date of birth": 1st millenium gets displayed as 1000, which is odd for a 9nth century person:
