I'm trying to get rid of an odd white line that keeps appearing at the bottom of my header's navbar. The navbar has a dark background, but whenever I click on the toggler button, this strange white line shows up at the bottom.

In the image below, I've pointed out the elusive line that I am unable to trace back and want to remove:

The HTML index only consists of the Bootstrap initial template and the navbar template.
