Dont want "Posts Page"

Have a look at the page template dropdown. This will be in the Page Attributes settings section. If you don’t see this section on the page editing screen, enable it in screen options.

Building on lorro’s reply, maybe the template was accidentally changed to one that uses posts. If you can change it back to the original template you used (with the template dropdown mentioned above), that should help.

Another option is to look at Settings > Reading, and make sure the page in question isn’t set as the “Posts page.”

I hope this helps, but let us know if it’s still an issue!
