Service duration on calendar

I have set up the service and filled to running order with timings. My latest service is training for leadership. This is a 3hr session. When I link this with my calendar it only displays a 1hr service. People who are involved with this service are hopeful it will only be an hour long.

Is there a way I’m missing to set the service duration from planning that’s shows up on calendar?

Planning Services are defaulted to one hour. This currently cannot be changed.
