Issue: A ministry is missing from the Scheduling Options > Ministers Needed area (and is therefore not getting scheduled in the auto-scheduling), while they are still showing in the Configuration.
Solution: This is a display issue that can be corrected.
Because they were still in Configuration, but were not displaying from the Ministry Scheduler > Scheduling Options > Ministers Needed, we knew that they needed their display reset. to do this we:
Went to Configuration > Selected the applicable Group > Selected the Applicable Event > Selected the Ministry > clicked the edit (pencil) button > Clicked Save, and then we repeated this for any other missing Ministries.
