Unable to delete a shared folder

Hello, I just noticed that I am unable to delete any Shared Folder. The delete button is not even there.

I am logged in as Admin and I have read/write box ticket. I am able to delete any folder/file under those shared folders.

From this article https://support.ugnas.com/knowledgecenter/#/detail/eyJpZCI6MTU5LCJ0eXBlIjoidGFnMDAxIiwicGF0aENvZGUiOiJwcm8wMDEsbmo0cHQ3LGhsbGNsZCIsImxhbmd1YWdlIjoiZW4tVVMiLCJjbGllbnRUeXBlIjoiUEMiLCJhcnRpY2xlVmVyc2lvbiI6IiJ9

It should be straightforward. What am I missing?
