You have closed this account. It remains in the system because you have transactions which still refer to it, but it is not shown in the views. You can make it visible again by going to the View menu and selecting Show all accounts or by deselecting the Do not show closed accounts setting.
Pechou esta conta. Aínda segue no sistema porque hai asentos que se refiren a ela, pero non é mostrada nas vistas. Pode facela visíbel de novo indo ao menú Vista e escollendo Mostrar todas as contas ou desmarcando a opción Non mostrar as contas pechadas na configuración.
