Question about Spell Specialist Archetype for Arcanist

[FernGully]

Short Description:

Signature Spells

At 1st level and each time a spell specialist gains a new spell level, she chooses a signature spell. The spell specialist can cast this spell without preparing it, in the same way a sorcerer casts spells spontaneously. Even though the spell specialist does not need to prepare this spell, it still counts against the number of spells she can prepare, reducing the number of spells of each level she can prepare each day by 1. A spell specialist can swap out a single signature spell for another spell of the same level when gaining a class level.

I guess this means that all levels of prepared spells are reduced by 1, INCLUDING cantrips?

As written, yes. As intended, hard to say - it could easily have been written without considering the fact that you have two levels of spells available to you at 1st level. If you've got a regular GM I'd just ask.
