Totem Pokemon have incorrect abilities

[merfed]

They currently have the abilities of their base form when Bulbapedia states: "The Ability is the species' Hidden Ability if the species has two standard Abilities, and the species' sole standard Ability otherwise".

Technically they aren't incorrect, the game data lists all abilities of the non-totem pokemon on the totem form's data as well. This repo simply doesn't differentiate between obtainable and unobtainable abilities (the same applies, for example, to the hidden abilities of some legendaries, or unreleased hidden abilities in generation 5)
