Just when I think the dumpster fire of a Hertz website can't get any worse...

I can log in to my account fine. Want to go look at a reservation I previously made so go to the menu on top: Manage Rental > View/Modify/Cancel Reservation.
It goes to what looks like a different website interface where I am no longer logged in and wants me to enter the confirmation number and name for the reservation to look it up.

Why do I have to log in to this 'other' UI? The interface is almost useless as well, and I noticed at the bottom it has a 'C 2022' instead of the normal website showing 'C 2024'. Seriously? What absolute garbage
