Summoner Skills not working properly

When creating a new Summoner, the Class skills are not displayed in most cases.
Only the first two times I had the right skills but now when I try to make a new Summoner, they don't show up.
I also have weird modifiers (-7,-11 misc modifier on a fresh character) and it once said that ONLY Fly was a Skill Class (with -7 misc).

Steps to reproduce:
-Load Pathfinder RPG Core Supplements
-Create a new character
-Add at least 1 level in Summoner class
-Watch the Skills tab and enjoy
