An update for anyone with the same or similar problem:
I didn’t figure out root of the problem itself, but I did figure a fix. Simply deleting and then re-uploading the wordpress/xmlrpc.php file on my server and then deleting and re-entering my blog information/profile within Zoundry Raven took care of the issue(s).
That doesn’t really help me much since I’ve seen those pages. I simply want to know what those little codes are for the orderby. I can’t use them if I don’t know what they are. In other words, I want to change the default but I don’t know what to change it to. Unless, as you said, there’s a bug in the code.
Not that it matters much now. I downloaded Zoundry Raven and will be using that.
