I don't get what the problem is and how I can solve it.

Can you please help me?

Hi,

Either activate the "round prices during calculations" setting of the HikaShop configuration so that HikaShop calculates the total the same way PayPal does, or turn off the "send order details" of the PayPal payment method in order to only send the total and not the details of the cart. If you send the details, PayPal will recalculate the total itself and thus the HikaShop's caclulations need to be done the same way or there will be a mismatch with the roundings.
