Filesystems to include in local disk space

Hello

Being trying to figure out a way to show only disk space used on my sda1, having multiple drives. I have discovered the setting in "Virtualmin Configuration/ Status Collection", but somehow I am unable to set it up as I want.

I have setup to include only /home. (as shown in the attachment https://www.virtualmin.com/files/disk.png).

Tried /dev/sda1 also :)

Nothing seems to work. I still get the "Local Disk Space" shown for all hard drives.

Refreshed the system info. Did a reboot. Same info displayed.

Am I doing something wrong or this is not working?

Thank you
