The repository configuration is OK (pkg.ghostbsd.org)

The locale settings are clearly incorrect, and the fact that your changes aren't reflected most likely is because locale is also set in some other place, processed after your shell profile.

Possible places are:

display manager config files (unlikely if you are using slim)
.xinitrc
/etc/X11/xor.conf.d

may be others ...

try a brute force search:
That should tell you where these settings has been put in effect.

i386 arch will follow within 3 days.

i386 11.1 test repo is ready and available.

That command you gave me returns:

/etc/mtree/BSD.usr.dist: af_ZA.ISO8859-1
/etc/mtree/BSD.usr.dist: af_ZA.ISO8859-15
/etc/mtree/BSD.usr.dist: af_ZA.UTF-8

But this file contains other locales as well (It's too big to post here)

I'll switch to slim from lightdm and see what happens.

I switched to slim and all is well.
I remember now that my lightdm configuration was mangled after the update.
I'll see if I can find out why lightdm is doing this.
Thanks, ASX.

I made my ISO successfully after deleting grub-efi.

I installed the xfce-amd64 iso onto real hardware(my laptop).
I chose the ZFS file system.
It runs very well and perhaps a little faster than 11-ALPHA.

I don't know if this is just my ISO but:

png files have no thumbnails- they look like text files
I can't change the desktop background. If I choose other to choose a folder for my background picture all options are greyed out.
If I right-click on a png file there is no "Set as wallpaper" option.
Sometimes during boot it stops (freezes slightly) and goes back to grub and starts again and boots fine. According to the boot text the point at which it stops booting is right after the hard drive information is shown.

Like I said it runs great apart from these problems and maybe it's just my ISO.
I think I'll make another ISO and see what happens.
