I am entirely unable to change from anything other than default filters. I figured this was just a local issue but I talked to Jinte on #ffxi and he wasn't able to change either, so I don't think it's something on my end.
For what it's worth, I can't display more or less than 50 posts per page, that one doesn't change either.
