I meant, do i check anybox once i post the course?

for example new event yesterday was Disrupted Journeys, but it is not showing- (shows old Improv course from December)

https://www.uxinnercircle.com/courses/designing-for-disrupted-journeys/

before, it would automatically show last published masterclass (not others). Now i want it to show any past course (latest) automatically. What do i do back end WP?
