Indenting In Sidebar

I’m trying to use the Custom Menu Widget to set up a side navigation bar on the left of my website. It looks and works fine on one page, but on other pages the text is indented for some reason.

https://www.naturalcurrents.com/company it seems to work fine in, but when applying the same code to other pages, such as https://www.naturalcurrents.com/company/vision and https://www.naturalcurrents.com/products-services/ the text is indented all the way out. I’m kind of a beginner to webdesign, so sorry if the solution seems obvious.
