Samsung S4 WIFI Password 8 digits instead of 6 digits- Connect Grey out

Hiya,

By mistake I press 'forget this network' afterwards when I try to connect to my home wi-fi, it is asking for 8 digits password, whereas it is a 6 digits. The connect button stays grey out until I enter 8 digits which ofcourse is a wrong password. Help Please.
