Gaps in navbar

On my website https://www.wanpsacks.com , you can see how the navbar on top there us a huge gap between the “Comics” link and “Links” link. There’s even supposed to be another link to the right of that, but it’s been pushed off by the gap. I have a suspicion that it’s because I’ve added several pages underneath Comics, but they don’t appear, and I nested them underneath Comics so they wouldn’t show up in the first place. I hope it isn’t a problem with the theme, as I’ve already spent a good amount of time customizing it.
