Marriage List

I submitted to development last year that the marriage statistics that show are incorrect in some cases and they appear to agree. I Have submitted the marriage
Stats as shown on the plan and its quantity and the stats of marriages produced on a printed list. Both show different figures.
They acknowledge receipt but a "no Show" that this will be fixed!!
How long does it take to determine and correct this fault??
In the meantime be aware that in some cases the Stats on Plan do not agree with a printed list of the same.
