Charactermancer and Subraces...

Good morning, As you can see, I've purchased SCAG and MTOF...  If I choose a 'Dwarf' race, I would've thought I'd be able to see:  Gold Dwarf (SCAG), Shield Dwarf (SCAG),  Mountain Dwarf (PHB), Hill Dwarf (PHB), Duergar (Player Race)(MTOF), and Gray Dwarf (Duergar)(SCAG) given my marketplace investment.  However, Gold and Shield Dwarf do not show up.  Not an expectation, but I do see that Forgotten Realms also mentions an arctic dwarf, urdunnir, and wild dwarves that also don't show up, but are listed in forgotten realms material (not in the SCAG handbook though).    I wonder what is presenting the Gold and Shield Dwarf from appearing?  Or, do we just assume that a Gold is a Hill... and a Shield is a Mountain Dwarf?  Would be nice if the subrace actually matched SwordCoast races on the character sheet if we're playing Sword Coast.   Is this the case for everyone?  or, am I doing something wrong? Here's my options below when I choose 'Dwarf':

Additionally... if I select 'Elf'... NONE of the SwordCoast races appear - Dark Elf (Drow) appears, but as a reference to the PHB.  I would expect MOON and  SUN Elves to appear, but they don't. 

However... if look at 'Race' instead of 'Subrace'... all the SwordCoast subraces are included as Half-Elf variations.  This seems rather strange to me.  Anyone have thoughts?

From the SCAG Compendium/Book: Shield Dwarves have the Racial Traits of Mountain Dwarves in the Player’s Handbook. Gold Dwarves have the Racial Traits of hill Dwarves in the Player’s Handbook.  Moon elves have the Racial Traits of high elves in the Player’s Handbook. Sun elves have the Racial Traits of high elves in the Player’s Handbook.  As for the half elf varieties, I assume it was just easier to program that way.
