Availability Distribution-days, week & month: not monito

I have recently upgraded to Build: 7205 on a Windows 2003 (VM) server.

And now from the Home screen the Availability Distribution chart don't seem to be reporting correctly for some options:

Last 12 hours: Green
Last 24 hours: Green
Today: Green
Yesterday: Green
Last 7 days: Blue (not monitored) for the past 4 days
Last 30 days: Blue (not monitored) for the past 4 days
This Week: Blue (not monitored) for the past 2 days
Last Week: Blue (not monitored) for the last 2 days
This month: Blue (not monitored) for the past 4 days
Last Month: Displays correctly

It seems to be a problem with the way the data is being seen by the different chart options in OpManager not the quality/accuracy of it.

I have run DBRepair.bat with no change, I think the database is ok indicated by the first few chart options?

Any ideas?
