Partition Manager gives screwy partition sizes for a partitioned RAID device.
Specifically, my RAID5 of 750GiB, /dev/md127 has 4 primary MBR-style partitions.
Partition shows /dev/md127p4 (ext4 /home) as 203.66GiB used of 75.87GiB.
df -h shows the correct sizes:
/dev/md127p4    598G  204G  364G  36% /home
so it appears the used figure is right, but the partition size is a figment of its imagination.

SOFTWARE/OS VERSIONS
KDE apps: 19.08.3
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.64
Qt Version: 5.13.2
KPM Core: 4.0.1

ADDITIONAL INFORMATION
The underlying disks are also MBR partitioned.
Looks slightly different to bu 396776, which gets the total size right.

Partition manager used to get it right - not sure when the problem started.
