Before I start, let me say I don't know much about IPCC and I know next to nothing about Historical Reporting.

I have a customer who has come to me with problems on their IPCC server and has said they are getting errors/differences in their reports when they run a 1 month report and a 3 month report. They have provided me with some screenshots which are attached.

When they run a 1 month report for the month of January this year, they get 1 line per date for the month. When they run a 3 month report they are getting multiple lines per date for the month.

See the attached screenshots "1month.png" for the 1 month report, and "3month.png" for the 3 month report.

Why are they getting multiple lines when running a 3 month report, but not when they run a 1 month report.

If it matters, this is a redundant server (master-slave) IPCC setup.

Thanks in advance.
