The api calls to fetch the two json files are really slow, it's causing a flash of unstyled content whenever you click to get a new page. Are you polling the bitshares client directly for the order history on the backend? If so that is probably why, the order history rpc call is really slow so you should probably cache the data.
It's also a little hard to figure out what's actually happening in those transactions. You could probably include blockchain.info links as well for the BTC transactions?
