right sidebar bug in anaconda theme

I recently changed my theme to anaconda, but on the home page of the blog, the right sidebar extends into the header. This, however, does not occur on other pages like “archives,” “contact me,” or on the page after one has clicked on a post title to see that post alone.

Does anyone know why this might be occurring and what I can do to fix it? The blog can be seen at https://proclamation.onethingiknow.net/
