HP-UX Disk-Utilisation Monitor show not all Filesystems

Hi App-Support!

If i look in AppManager on a monitored HP-UX Machine, under Disk-Utilisation, it shows not all existing file systems!
It only shows:
/usr
null
/stand
/var
/tmp
/opt
/

But if i look on the machine the df -f Output brings this back:
$ df -f
/u07 (/dev/vx/dsk/pacsdg/orb-pacs-db-vol01): 578998546 blocks
/u06 (/dev/vx/dsk/pacsdg/orb-pacs-redo-vol01): 96986526 blocks

/stand (/dev/vg00/lvol1): 382960 blocks
/ (/dev/vg00/lvol3): 480832 blocks

Whats going wrong?
