OSX Wrong symbols in text.

While have someone point out bugs in the first edit draft of my book I have come across a strange font bug.

In the text above, you will notice that two different set of speech/quote marks are in use. I’m not sure what happening and I want it to stop. I am trying to write a book in the old font style using the 66/99 style marks instead of the ”” marks.
Has anyone out there got enough experience on how to fix this is OSX 10.9.2 and Pages 5.2 (2013/14) version.
