Ruined portals generate horizontal

This is on Nintendo switch but not sure about other versions. I was checking out the experimental with wild update. And I came across a ruined portal that generated horizontal. I'm not sure if this carries over to non-experimental world I'll post a comment when I do. But I don't think this is intended to happen. I never heard that this could happen if it does happen. Then close this. I'm just not sure about this.
