Memory Snapshot BUG

By accessing OpManager has a widget that shows the servers with higher consumption of Memory. I checked the server with this high consumption of memory, but click and go to the snapshot of the server memory used this with almost no use.

clicked on the vm and monitor performance information shown is not correct

the information shown on widget is correct

I generated a report from memory on this server and the information displayed is correct

clicked on the monitor performance and tested the monitor information displayed is correct

What is not correct is the information shown in the snapshot must be some BUG
