Hi I got this issue when i made date/time field Shift Start Time and Shift End time on Volunteer Shift Worker Object.So instead of makeing Date/time Filed it should be a formula field of type date/time.Refer below for fomulas of Shift Start time and Shift End time
Shift Start time: Volunteer_Shift__r.Shift_Start_Time__c Shift End Time: Volunteer_Shift__r.Shift_End_Time__c
