WordPress redirecting weirdly

So I have this page named “test” on my localhost.

Every time I try access the page by entering “http://localhost:8888/wordpress/test” it will redirect me to “http://localhost:8888/wordpress/test/” (with a trailing slash) and instead of a page that I designed, it actually gave me a directory listing page.

I have not mess with any .htcaccess file and I have no idea why it is acting this way, as it is working fine few days before.

Anyone have any idea where I should try to look into to solve this problem?

Edit: when I try to change the page name to something else it works just fine, but I have no idea why it will just redirect when i use “test” as the page name.
