Yep.
Are you certain that this was your spell school of specialization? It is not sufficient to have SF or GSF in illusion.
Yes, it was the school of specialisation, not merely SF.
This is still an issue. I'm offered some themes: Spiders, rats, etc, but not the illusion nor shadow theme. The character's name is "Thraluril Galiana"
As a semi-separate issue, he is a sun elf and should have 20 INT and 10 DEX, but instead he has 22 INT and 8 DEX
