No folder permission options/lock icon in macOS Catalina

On a 2018 Mac mini that came pre-loaded with macOS Catalina, when I get info on a folder, under "Sharing & Permissions" it only displays "You can read and write" but there are none of the standard read/write columns nor any lock icon like in previous versions.

What am I missing? Am I not logged in as administrator? I've never encountered this before.

The permissions you see will depend how the drive is formatted.

If it's HFS+ or APFS, on any non-boot drive, you should see a line at the bottom of the Get Info window marked "ignore ownership on this volume'. If it's NTFS this will be missing. Any kind of FAT & it will also be missing, along with the entire permissions 'box' which would usually be at the bottom.
NTFS cannot hold the full set of unix/Mac permissions & FAT can't hold any of them.

See this example, from left to right APFS boot drive, HFS+, NTFS & FAT32.
I also have Paragon NTFS for Mac installed, which allows writing to NTFS [which the Mac cannot do natively] & which may affect how the permissions show for NTFS [I'm not certain].
