Best procedure for single event with 3 type of tickets

Hello, I need support for my website
I have 1 single event span over 2 days with 3 type of tickets: daily (day 1), daily (day 2), 2 days pass

Is it better to make one event with 3 different type of tickets or add dates to the original events? (this create 3 equal events?)
Now I have a single event with 3 type of tickets but in a simulation, I have strange results (see the picture)



In the event the price is set to 0€, each ticket type has its own price setup
if I put the price in the event configuration, this will be summed to the other ticket value...
