Can’t Delete Pages

Using WordPress for a blog at:

https://www.themovieblog.com/godofwar

I’ve created a few pages in the Manage – Pages area.

The problem is I’d like to delete a couple of those pages. So, under the “Action” column, I hit “Delete”. The page then disappears from the Pages list.

But when I go to look at my Home Page, the page I deleted is STILL listed in the navigation. When i go back to the Manage – Pages area, that page I deleted is back on the list!

I keep deleting it, it disappears, but when i refresh the Pages list, it appears again.

Any help here would be appreciated.
