Wrong service's schedule showing?

I'm using the following shortcode to display a schedule:

[app_pagination][app_schedule service="5" class="twentyfourhour" logged="Click on an orange time slot to reserve equipment."][app_confirmation]

However, the schedule is showing for the service with ID# 4, not 5.

This is the page where it's displayed: http://tmi.friendlyweb.us/core-facilities/equipment/time-flight-secondary-ion-mass-spectrometer-tof-sims/

I'm in testing phase so I'd normally try to delete and reinstate the service(s) but I don't see any way to delete services once they've been created. Thanks for your help!
