Cannot change campaign state

I have previously completed the campaign with another one of my characters and want to skip the Lord of Hatred campaign with one of my other characters. However, I do not have the option to do so. When I log on to said character I have the quest prompt to find the entrance to Temis but the thing is, I have the waypoint already and am standing in the middle of town. This character did used to be seasonal and is now eternal, not sure if that would cause this. I am just trying to use the cube on my character without having to replay the entire expansion when I’ve already done it. Several other of my characters have the change campaign state option but this one does not. Please help.
