It is certainly confusing. As a newcomer, all I heard about was Harvester, so looking at Rancher in the first login made little sense to me. Furthermore, there different states of dashboard redirection does not help any better (2 dashboards on the same IP and port?)
Harvester seems to be an interesting product with some learning curve at the beginning. Putting the not-so-greaf initial UX aside, I'm excited to learn more about this product.
