ACL hide folders

After updating from 2.2.22 to 2.2.33 rsp 2.3.8 my ACLs went bust.

Below line in the global acl file hides all folders except INBOX for all users

• group=ALL

Next reenable certain folders, eg:

Sent group=ALL lrwsi

This made anyone see "Sent" in 2.2.22, but no longer so in 2.2.33

Any ideas how to have it like before?
