Disk Usage widget won't display SSD percentage used

I have a new install of Neon on this computer. I want to use the Disk Usage widget to display the percentage used for each of my hard drives on it. My home partition is on an HDD and shows the percentage just fine. But my root partition is on an SSD and I can’t select SDA3 from the list, I only see SDA. The options for that are Read Rate, Total Space and Write Rate. Why can’t I see the individual partitions? I have SSDs on other computers and the widget shows their partitions just fine.

The file system for root is ext4, the file system for home is btrfs. The NTFS partitions on a third drive aren’t showing up as options either.

I’ve resolved the issue. I wiped he disk and installed Fedora KDE instead. Now my widget shows all the drives I want.
