Mathbot limitations which updates this list of mathematicians gets the dates of birth and country from categories for example at Archimedes the country is Ancient Greece and the birth year is 287 Any modifications to dates and countries like these will unfortunately be overwritten with information from the categories in the Archimedes articles and the others This is by design seems that keeping the mathematicians articles with their entries in this list is the better thing to do But then if you want to change something about dates or country you should not do it here where information will be overwritten but in the articles themselves Thanks
