PayPal fee is applied but no payment method selected on checkout.

Steps to reproduce:
1- Start a purchase, go to checkout and select paypal as payment method.
2- Logout
3- Login again and go to cart
4- Proceed to checkout to billing step

Expected result:
Fee is applied when paypal payment method is selected and no fee is applied when logout and login again because no payment method must be selected when login again.

After login, the fee is applied in cart. When the user proceed to checkout, no payment method is selected but paypal fee is applied.
The fee is applied even when login again using private navigation.
