When global FP is set to block, site FP could be allow or block. default becomes block.
When global FP is set to default, site FP could be allow, block or default.
When global FP is set to allow, site FP could be allow or block. default becomes allow.
That means, site FP's default always follow global FP.
When site FP has default, Preferences file doesn't include its setting. Because of this, global settings is applied. This is expected behavior because setting default means deleting current setting.
So, global setting is effective value. => Fixed by using secondary pattern(balanced) instead of using DEFAULT.
