btop shows error in disk usage

[Philius-users]

hello
i have a 2tb raid0 with 2 1tb disks (75gb used)
i have a single 2tb usb disk for my backups (75gb used)
i have a 1tb network drive via cifs

btop writes 160gb used for root and 160gb used for usb and not 75gb ???

for efi partition and network drive it's ok

sometimes for 2 seconds btop writes 75gb for root
when i go to btop options and i modify, btop can display 75gb for root and usb
