The Missionary Progress Record became available to the Ward Council in Sept. 2017 (see:
https://www.lds.org/mls/mbr/report/progress-record)
The data for the report is pulled from the missionaries Area Book Planner database.
When the report became available, I noticed that there were out-of-date entries on the report. (Converts who had been baptized and moved out of the ward.) I repeatedly asked the Full-Time missionaries serving in my ward to clean up the data in their Area Book Planner database so that we could make effective use of the Missionary Progress Record in our Ward Council meeting. The missionaries were unable to remove the obsolete entries. I spoke with the mission office (Salt Lake City East Mission), they couldn't help. The missionaries asked their mission president, still no resolution.
In early January 2018, I contacted the Global Service Center regarding this issue, and they opened a service ticket (number INC05059740). The service ticket was "Escalated to the ICS from GSC: GSC01678380".
The obsolete data is still showing on the Missionary Progress Record, and the current missionaries in my ward have confirmed that they can't delete or change the obsolete data using their Area Book Planner application.
Perhaps if other wards and/or missionaries report this problem with the Missionary Progress record and the Area Book Planner application, the problem will get some attention and be fixed.
