Change event calendar page title

After many hours reading posts on the event calendar site I cannot figure out how to change the title on https://bkec.info/events/ from “Archives”. Could someone please help me? This is a school non-profit site with limited funds so buying a yearly license for $89 per year isn’t an option to get support from theeventscalendar.com.

Thanks
