Stuck figuring out an alignment issue (bug?) on a CMS template page

Hi all! New Webflower, here.

I’m running into an issue I can’t figure out for the life of me.

I followed this tutorial to produce a dynamic table of contents sidebar for my client’s blog articles.

When I finished designing the page and went to test it, the preview link bumps down two divs – my content wrapper and my author wrapper – but leaves the TOC wrapper at its appropriate position.

I’m sure I’ve overlooked something simple, but any help would be greatly appreciated.

Thanks in advance!
