permalink question

hi everyone,

i’m trying to rename a page using permalinks, and everytime I do, the page gets renamed to have -2 added to it. I don’t have a page named what I’m trying to change this one to, though – I’m trying to make /store, but it keeps getting changed to /store-2. Is there some kind of cached data that is remembering a past time I’d created a page named this and then changed it? Is there a way to fix this? Thanks.
