Trailing Slash on URLs

Hi, not sure how this happened but I ran an audit on my website and it shows redirects of all my pages which end without Trailing Slash and redirects them to the same page ending with Trailing Slash on URLs.

I check on Google site:websiteurl.com and it shows me all indexed pages and they all have trailing slash at the end. So no url without a trailing slash is indexed.

If I run a redirect checked (example with https://httpstatus.io/) it shows me X-Redirect-By WordPress when I search for an url on my site without a trailing slash.

Example:

(301) htts://websiteurl.com/my-page
(200) htts://websiteurl.com/my-page/

Regardless of how this happened, is there any way I can remove these redirects? where are they located within wordpress – I don’t have an seo plugin so I guess it was via permalinks? I just don’t know how to remove these redirects so that they stop appearing on my audits via Screaming Frog or Semrush, etc.
