Strange Sharing Issue - No 'Can Delete' Option on Random Folders?

Newly upgraded 16.0.1 install running on Ubuntu 16.04. I don’t recall ever seeing this issue before, but as screenshots show there are random folders where there is no “can delete” option when sharing the folder with other NC users. In this case, these are 2 different folders inside a single folder. This is on CIFS mounted storage and permissions to the folders outside of NC are identical. Anyone every seen such a thing? Very odd!

I have a similar problem. I was using Nextcloud for a project and uploaded a lot of files, now I cannot delete or move any files in the shared folders. I can copy, download, etc.
I am running Nextcloud in a docker on an Unraid server
