Can't hide a completed order from My Ebay

[jghere]

I have two finished orders that simply won't go away from my visible order history.  I can hide them, but they always re-appear when I go back to My Ebay page.  Both orders are for two or more items bought at once from the same seller.  Every time I see them I hide them and they soon show up again.  Not so with single item purchases.  Whats this about?
