I was going to suggest a lot of things that you did. Their mobile backend seems to have some kind of caching layer (it's pretty common for changes to bookings to take several minutes before you can see them in the app), and it's possible this is keeping other stuff around.
Amusingly, even with 22 active bookings, and the high rate of booking/changing/cancelling I do, I am not experiencing any of the issues you are.
