OpManager Mount Point monitoring not showing accurate data

We are running the current version (10200) and followed the instructions to enable mount point monitioring ( http://support.opmanager.com/sd/AddSolution.sd?solID=36001). But after that is done all drives (mount points and local disk) all show the same percentage open. For example we have an Exchange server that has 3 local drives and 14 mount points and all drives are showing are showing that they are at 75% capacity, when in reality their capacity varies greatly but some are nearing full. All of our servers with mounts points have the same issue. Any other server is working as expected, but when you have hundreds of servers with mount points that is not comforting.
