Referrals shows the same site

Hi, I’m wondering what can cause referrers be the same as the page we are examining? This happens in transitions and in users flow and if I use referrers in custom reports.

i.e. the user flow is page 1 > page 2 > page 3 but the referrers show for page 2 that the visit came from page 2 (in addition to page 1 which is correct). In transitions these same page referrals appear in websites or internal pages.

I don’t think reloading the page should cause this and the pages I checked don’t include links to the same page.
