My b2evolution Version: 2.x

My blog is setup to display as simply index.php. But when I hit the Next link at the bottom to show the next page the URL becomes "index.php?blog=1&paged=2". Manually changing the URL to "index.php?paged=2" gives me the exact same page. I'd like the Next and Previous links not to have "blog=1", but I can't figure out how to remove it. I suspect it's in this line of code in index.main.php:

'links_format' => '$prev$ :: $next$',

I've poked around, but I couldn't figure out exactly where to change the "prev" and "next" bits. Of course, I know just enough php to be dangerous. ;)

Any suggestions would be most welcome.
