Device Storage looks off in File Manager

Hello, I'm a new user of Bazzite, trying KDE. I followed the video tutorial from Mike's Tech Tips on Youtube to dual boot. I am concerned, as my device storage does not look right to me, and I want to check what's up. Screenshot is attached of the Device Storage from the file manager, and of the detail panel for the / device.

Looking forward to an expert's eye on the matter, thanks!
