Can't Change the Slug with the Wiki Plugin

I’m using the Wiki plugin and it keeps on changing slugs on me.

I’ll create a page titled “Foo Bar” and work on it happily. The slug is “foo-bar” like it should be.

However, when I publish the wiki, sometimes it will change the slug to “foo-bar-2” even though I do not nor never have had a different “foo-bar” page or post – even on other post types.

What’s worse, is the Wiki plugin then won’t let me change the slug – even though I can change the slug on every other post type.

I have a very specific hierarchy with the Wiki I’m working on and strive for pretty permalinks. I would like to be able to modify the slugs since the Wiki plugin keeps on trying to make them ugly.

Didn’t see any posts on this topic elsewhere in the forums.
