URL – Google Analytics showing the path of the previous page as the current page

My data shows that for one of my pages, Path of the previous page and page are identical. After Googling, I see that this may be due to updates or page updates.

I've tried to test this, by downloading / refreshing about 20 times on the page. My pageviews for this combination / previous page path only increased by 1 in the custom report, not the 20 that I was expecting.

Ideas why?
