Wordpress adding -2 to the permalink, how to find the original page

I've been racking my brains on this, and about to lose the will to live really.

I have been creating a bunch of pages last night, and i noticed most of them are adding 2 to the permalink, i understand this means duplication, but that's the thing it's not. If you type in the origninal link, it redirects to homepage, i check out sitemap, nothing.

I have checked rankmath redirections, nothing there either. Google isn't really much help. I just had a chat with the hosting and they say it's wordpress related.

Any help please, i am stuck at this point,

Go to Trash section and remove all the deleted post/pages. After that you won't get -2 permalink.
