Something possessed me to enable one of the "SRD Pathfinder Adventure Path" options under Prior SRD Content when trying to use traits & flaws. When this is done, and the optional rule to use traits and flaws is not enabled, it messes up the display on the "Feats" tab for the character. It displays the "add new trait" button, but it overlaps/sits on top of the list of feats. Also, this button doesn't do anything when clicked on.
It does work however when optional rule to use traits and flaws is enabled.
