NTFS not detected when mounted via gui

[jrabbit]

I have an ntfs partition mounted that is detected as "fuseblk" and nothing further. I'd expect duf to recognize NTFS here. lsblk reports it as ntfs correctly. I mounted it using nautilus in gnome-shell.

Have the same issue:

 {
  "device": "/dev/sdb2",
  "device_type": "fuse",
  "mount_point": "/mnt/windows",
  "fs_type": "fuseblk",
  "type": "fuseblk",
  "opts": "rw,nosuid,nodev,relatime",
  "total": 1000068870144,
  "free": 776833372160,
  "used": 223235497984,
  "inodes": 759805988,
  "inodes_free": 759803808,
  "inodes_used": 2180,
  "blocks": 244157439,
  "block_size": 4096
 }

I guess "fs_type" should be "ntfs" here?
