I noticed a minor bug on initial page permalinks when creating new pages as drafts from the tree view below the 2nd level.
Example: I have a Level-1 page and a Level-2 page child of Level-1. When I create a new page as draft inside Level-2, let's call it Level-3, I got the wrong permalink
However, after saving the page and reloading it, the permalink goes right as it should, so it's only a transient problem.
This also happens for deeper levels, i.e.
It only occurs for drafts and not for published page.
