Listing users from Windows Properties window shows only some users

Hi,
As stated.
Please refer to the image pasted there : https://pasteboard.co/IzY8vnB.png
A. is the groups windows shows me (nasb IS my FreeNAS).
B. is the FreeNAS Groups

Why does it only show some of my groups, and some that are not in the FreeNAS (Administrators, Users, Guests) ?
I'd understand if he'd show none... it's not a Windows server... but some ?

Note that the exact same question applies to users :)

BUILTIN\administrators, BUILTIN\users, BUILTIN\guests are automaticatically generated by winbindd and visible in net groupmap list.

Alright, thanks, but what about the missing groups then ?

In the Windows list, only 3 of my FreeNAS groups appears : rh, info and direction... is there some parameter that makes them available to a Windows client ?

bump ?

EDIT: I must admit these three visible groups on Windows were added in the FreeNAS after doing an upgrade from 9.2.1.6 to 11.2 !! Just realized this.
Should I simply recreate all groups ?
Or could I tweak a setting to make these "old groups" available in Windows ?
EDIT2: Recreating a group and giving it the same GUID does not work (note that FreeNAS gives the same GUID by default because the GUID was just freed by the deletion of the group).
Now, deleting the group and recreating it with a different GUID works ! It now appears as a group in a Windows client.

Maybe a bug due to the upgrade ?
