Surprised no-one has spotted this Oracle: Ancient Lorekeeper "thing"

[Doki-Chan]

I'm not sure if this is correct or not, so I'm asking here first: Oracle Ancient Lorekeeper Archetype states the following:

"Elven Arcana (Ex)
At 2nd level, an ancient lorekeeper’s mastery of elven legends and philosophy has allowed her to master one spell used by elven wizards. She selects one spell from the sorcerer/wizard spell list that is at least one level lower than the highest-level oracle spell she can cast. The ancient lorekeeper gains this as a bonus spell known. The spell is treated as one level higher than its true level for all purposes.
The ancient lorekeeper may choose an additional spell at 4th, 6th, 8th, 10th, 12th, 14th, 16th, and 18th levels.
(emphasis mine on bolded text)

This ability replaces the bonus spells she would normally gain at these levels from her chosen mystery."

The text from the rules above, seems to imply you have to only choose the cantrip (SL-1 spell) for your Level 2 bonus spell, and then you MAY sub in one of the SL-1 Sor/Wiz spells for an even level Mystery one if you want... (i.e. anything above the first is optional...)

However, in the Oracle Tab on the HL character when you choose this archetype, it states you MUST choose a spell for each bonus spell slot, and automatically wipes out any from your Mystery List.

(also that makes the droplist completely wrong as well if you are designing a level 10 oracle as it dumps the whole list of spells, not just the ones at SL-1 at that SL in the list, making the early ones hard to differentiate between to pick from first...)

Which is the correct interpretation?

The ruling would probably need to be found on the Paizo forums, as to the official ruling for Pathfinder (rather than the implementation within HL).
