Calendar showing events from 2013

I’m trying to help a friend with her site. Since she updated the All In One calendar it’s showing events from May/June 2013 and it won’t advance past June however in WP Events I can see all the recent events that she created and publish dates are all there but they don’t display in calendar. Any suggestions would be greatly appreciated!
