Select "open in new card".
On the new card a "close" button is visible.
If the account name visible on this new card is too long the "parameters" button can't fit properly between the long name and the "close button" : it's pushed down.
If you click on the "close" button a blank card remains.
The best option would be to remove the "close" button altogether from the new card : slide up is the best way to close on Webos and the account cards of Project Macaw are working that way already.
