The list of options for humanoid Favored Enemies is in error, presenting a scattering of races from multiple sources, but not all from any one source.

The options presented in the creator are:

Dragonborn,    Dwarves,         Elves,
Gnolls,              Gnomes,         Goblinoids,
Grimlock,         Haflings,         Humans,
Kobolds,           Lizardfolk,      Merfolk,
Orcs,                 Sahuagin,       Werebears,
Wereboars,      Wererats,        Werewolves,

Whereas the options from the core 3 books are:
Player's Handbook                                                           Dungeon Master's Guide                                                    Monster Manual

Dragonborn,    Dwarves,        Elves,                                 Aarakocra,         Aasimar,         Bullywug,                          Aarakocra,             Bullywug,        Dwarf,
Half-Elf,            Half-Orc,         Halfling,                            Elf,                      Gnoll,               Gnome,                              Elf,                          Gith,                 Gnoll,
Human,            Tiefling,                                                     Goblin,                Grimlock,        Hobgoblin,                        Gnome,                  Goblinoid,       Grimlock,
                                                                                             Kenku,                Kobold,            Kuo-Toa,                            Human,                 Kenku,             Kobold,
                                                                                             Lizardfolk,          Merfolk,          Orc,                                    Kuo-Toa,                Lizardfolk,       Merfolk,
                                                                                             Skeleton,            Troglodyte,     Zombie,                             Orc,                        Quaggoth,       Sahuagin,
                                                                                                                                                                                              Shapechanger,     Thri-Keen,       Troglodyte,
                                                                                                                                                                                              Yuan-Ti,

The entirety of at least one of the lists above should be what is presented.

So the missing ones are: half-elf, half-orc, tiefling, aarakocra, aasimar, bullywug, grimlock, kenku, kuo-toa, troglodyte, gith, quaggoth, shapechanger, thri-keen, yuan-ti

Left out hobgoblin since it's a goblinoid, skeleton and zombie since they're undead.

I would class half-elf, half-orc, tiefling and aasimar as humans since they are usually born to humans.  This would make the entire PHB list included within the options, but I agree that some of the missing ones should be included as well.

Races from supplement books should be included too. Particularly ravnica and eberron races.

@DxJxC I opted to focus only on the core 3, until we know which sets will be added (strictly monster options, or monster and player races).

Though feel free to list the options from the supplements as well if you think it to be currently critical.

 I dont think it is critical at all. So far my group has only had 2 rangers and neither of them chose humanoids.
