samba - Jan 2021 - Permissions issue on only some files in a share

I'm seeing something I'm baffled? by.? I've mounted a samba share on
an OS X system and SOME files in the share are not accessable. I have an example
below.

the setting from smb.conf for the share:

 ??? csc policy = disable
 ??? read list = %U
 ??? preserve case = no
 ??? hide unreadable = No
 ??? write list = %U
 ??? posix locking = No
 ??? guest ok = Yes
 ??? hide dot files = no
 ??? case sensitive = yes
 ??? oplocks = Yes
 ??? map archive = no
 ??? writable = yes
 ??? locking = No
 ??? path = %H
 ??? block size = 1024
 ??? valid users = %S
 ??? hide special files = No
 ??? short preserve case = no


Seen at the OS X Client (10.13.6):

d??????????? ? ???????? ?????????????? ???????????? ? .VirtualBox

On newer versions the file isn't even visible


On the actual Filesystem:

drwx------??? 2 user user ????? 4096 Jan 12? 2016 .VirtualBox

Samba version:? samba 4.2.10


I've tried setting the directory to 777 as well with no change


debug level set to 4 for the client log shows:

 ? get_privileges: No privileges assigned to SID
[S-1-5-21-3503858573-3253549328-247812220-1003]

when attempting to access the files/directories


Any suggestions?
