Upon creating a Kineticist and increasing level to 7 and selecting Air as the Expanded Element, none of the Utility/Infusion Wild Talents appropriate to the Expanded Element become available, not even the ones that are well below the -4 level penalty. Even upon increasing the character's level to 20, none of the Utility/Wild Talents are available to obtain with the exception of those available based upon the Primary Element. The character in the attached screenshot is level 10, for reference. When attempting to choose any Talents that should be available, an error stating "You do not meet the prerequisites required to take this ability." is shown, and each of the aforementioned Talents has a Requirement of "var: KineticistLVL_Air at least 1".
For increased clarity, I have all Paizo Publishing reference material loaded in PCGen, and am including the test dummy character file.
