Filter Question

[MacQ]

For years I have wondered this but never got around to asking. Why are the categories in the Zone and/or Global filter file different than the filters listed in the Filters tab (under File/Options)? The categories in the Zone/Global filter file include Hunt, Caution, Danger, Locate, Alert, Filtered, Email, but in the Filter tab, the list is Hunt, Caution, Danger, and Rare.

Filter File:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE seqfilters SYSTEM "seqfilters.dtd">
<seqfilters>
    <section name="Hunt">
    </section>
    <section name="Caution">
    </section>
    <section name="Danger">
    </section>
    <section name="Locate">
    </section>
    <section name="Alert">
    </section>
    <section name="Filtered">
    </section>
    <section name="Email">
    </section>
</seqfilters>
