I want to change the last year of this series

When I first added a series in the site I have settled the first year to last year period being 2014-2019, but the show last episode is actually from 2023, and I don't know how to change that in the page, there's no specific section to it, and I even added new episodes from after 2019, and it still is 2014-2019 in the page.
