Can’t scroll to top after clicking anchor link

After I click an anchor on this page:
http://somaticstudies.com/resources

I cannot scroll back to the top of the page, and I lose the sidebar content which only appears at the top of the page. I saw this:

Anchor link cutting off the page based on height of absolute positioned element

And I tried removing overflow:hidden (which would mess up my layout), but it didn’t help. I also don’t have height:0 anywhere. I am not sure what is causing it?

Thanks.
