Reconnect fails when a banner is received from the server

Hello,
I've the following error when reconnecting to an SFTP server that sends a banner before authentification.

---------------------------
Error
---------------------------
Received unexpected packet in response to authentication request, type 6468524 (unknown)
---------------------------
Registro de autenticación (véase registro de sesión para más detalles):
Usando el nombre de usuario «igrid64».

Autenticación fallida.
---------------------------
Aceptar Volver a conectar Ayuda
---------------------------

This only happens on reconnection. Sometimes if I click continue fast enough it will reconnect successfully. Also if I check the box for 'Don't show this message again' of the banner, I will always reconnect successfully.

I'll attach the log file of a few apttents.

I would like to know if this is a problem with the configuration of the banner?

Thanks
