WP adding two posts one right but the other one with some number on the end

When you create two posts with the same title, WP has to make them have different URLs.

Are these actually two different/separate posts with identical content? Do you see two separate posts under Posts in the dashboard?

And did you intentionally create these duplicate posts, or is that part of the problem?

No they don’t appear as two different posts under the posts section, and if you are talking about the duplicate post then, wordpress adds “-2” after the url not then random id. Like: https://www.dexlop.com/fun/funny-prank-ever-best-of-all-time-2/

i don’t understand whats the issue!
