How close access to sharing folder?

I can not find how to close the shared folder for the user , or users
help please


Access is granted to 5 users, but they are not visible in the editing rights, what did I do wrong?

I think there was a bug with the sharing email or sharing social app, when they are activated, the sharing information is broken. Disable the app, and it should be visible again. I think there is also a fix on the way and the next bugfix release is around the corner (probably next week).
