[SOLVED] automatically adds "-2" to my permalinks - every time I edit or post new pag

I'm having some problems with my permalinks. WP is adding a "-2" to the end of all of my permalinks - even when there is no other page with the same name. Every time I post a new page, and every time I edit, it puts a "-2" after whatever I type in the permalink window.

I don't have anything in the "Trash," all of my pages are published, and I can't change the permalink back.

If I change to a completely new name, it will work ok... but even if I try and change it back to the name that I need it adds "-2"

Any help?

It is only occurring on one installation:

www.northcoastimports.com

Here's an example of an edited page:
www.northcoastimports.com/cc/8dm/8365-2

UPDATE: Apparently, it only occurs when the permalink is a number. I just created a new test page with the permalink "test" and it worked okay. I also created a new test page with the permalink "9999" and it added a "-2"
