What's confusing to me about the card is how much it is swimming in the holder. Is that a non-standard slab? The top 'stay' (whatever the technical term is for that sliver of plastic) is so much further up than any of my holders, so that accounts for the up and down swimming, but look at how much room there is on the sides, too. Here's a random ebay screen grab with a much snugger overall fit for comparison...
