Speaker for the past shaman not counting as having revelation class feature

[danyray]

Shaman with speaker for the past archetype gain the folowing feature: "Revelations of the Past: At 4th, 6th, 12th, 14th, and 20th
levels, the speaker for the past can select a revelation from the
ancestor mystery or the time mystery. She uses her shaman
level as her oracle level for these révélations"

Herolab show it not having the revelation class feature and as a result not allowing feat like Extra revelation.

I think its an ommission and the intent of that archetype was to give the revelation class feature like an archetype that give Hexes, can take extra hexe.

Is it Something that can be fixed?

Thanks!
